FAQs on Types of Quadrilateral - Understanding Quadrilaterals
| 1. What are the different types of quadrilaterals? |  |
Ans. There are several types of quadrilaterals, including squares, rectangles, parallelograms, rhombuses, trapezoids, and kites. Each type has its own unique properties and characteristics.
| 2. How can you identify a square quadrilateral? | |
Ans. A square is a type of quadrilateral that has four equal sides and four right angles. To identify a square, you can measure the length of its sides and check if all sides are equal. Additionally, you can measure the angles using a protractor to ensure they are all 90 degrees.
| 3. What are the properties of a parallelogram? | |
Ans. A parallelogram is a quadrilateral with opposite sides that are parallel. Its properties include having opposite sides that are equal in length, opposite angles that are equal in measure, and consecutive angles that are supplementary (add up to 180 degrees).
| 4. How is a trapezoid different from other quadrilaterals? | |
Ans. A trapezoid is a quadrilateral that has only one pair of parallel sides. Unlike other quadrilaterals, such as squares or rectangles, which have all sides parallel, a trapezoid has only one pair of parallel sides. The other two sides are not parallel to each other.
| 5. What are the properties of a rhombus? | |
Ans. A rhombus is a quadrilateral with all four sides of equal length. Its properties include having opposite sides that are parallel, opposite angles that are equal in measure, and consecutive angles that are supplementary. Additionally, the diagonals of a rhombus bisect each other at right angles.

hello there welcome welcome to this
presentation from rising pearl hum apke
host aqua destroy first though I've
Kamala may we have just started a brand
new CD series 8 jabya discussing
quadrilaterals as it was the reverse of
number two after the heroes of episode
number one we talked about what is a
quadrilateral as I'm asking those types
of quadrilaterals key such a little so
let us get started now so we start
without doing a quick recap after a
decade of the last webisode when we
talked about what is a quadrilateral
quadrilateral Oso is a closed figure
formed by joining four non collinear
points in an order so I said okay those
two are gonna match our points these are
the homology if you have points a b c c
and d agrestic a km/hr points these are
the heroes though so we first join a b
then b C then C D and D a whose order
may then we get a we get a closed figure
like this which has four sides a b b c c
d da and char corner a b c d and four
angles angle a angle B angle C and angle
D so yeah those times I close figure
Milty here this is what we call as
quadrilateral ABCD and you say we write
it like this quadrilateral a b c d so
those and these are the unique things
about quadrilateral four corners four
sides four angles so adds those that we
are going to talk about different types
of quadrilateral scheme so those for now
today let us quickly take a look but
before that we just wanted to share with
you one other thing also so absolutely
why are you talking about quadrilaterals
why we started this series
quadrilaterals optically those are
actually surprisingly enough most of the
things Johan take the hair use cut their
manager K blackboard say school he desk
school key the top of the chair arcade
notebooks
Kuki picture frame etc etc lusco most of
the things job big deal you look at them
and you see that they actually have four
sides right so they are all
quadrilaterals so we wanted to talk a
lot about quadrilaterals and maybe now
we will talk about some of the specific
unique types of quadrilaterals such a
little so let us find out now these are
those the different types shapes of
quadrilaterals a pitch is notice ki
jagah those Co you happy we have drawn
some quadrilaterals or the unique thing
is Oscar even though up the Haga ages
shapes have till you say getting this is
our first this is our second this is our
third and it's ordered megaria Hamada
fourth head you have fifth you have 6
and this is 7 up typically the slope you
just sat on a shapes you have a draw key
head they all have four sites like 1 2 3
4 1 2 3 4 1 2 3 4 1 2 3 4 1 2 3 4 1 2 3
4 1 2 3 4
yep these all are quadrilaterals those
two but clearly up they Kapoor
Moloch shall rahib these shapes look so
different so I'm having a character so
you're gonna take a look at each one of
them and they are going to go in detail
so paheli cheese those the Chupke he
Hamas like a hangar Keiko a question may
have a problem if we are going to draw a
quadrilateral either if it is a if it is
a if it is only a quadrilateral those go
the way you want to draw is you want to
draw it like this I pick your XID I pick
a bra straight line like this and then
back it is athena side ahead oh so
you're going to draw it in such a way
that none of them are parallel to any
other side and they are not equal also
so this is the best way and the most
generic with those ways of drawing a
quadrilateral that is you draws a pick a
straight line draw a base me and then
back Athena side scale go so you draw
them in such a way that these three
sides are not parallel and they are not
equal in length
naturally those allow
with that said Abby we are going to
start talking about each one of these
ones so 2 3 4 5 6 7 we are going to look
at each one of them and find out key
what they are so those are a hamari
second figure now this is what is called
as a trapezium or a trapezium so what it
is those three it is a special type of
quadrilateral Jalopy it has one pair of
opposite sides parallel so that
obviously say if you write this as a b c
d if you write this as a b c d those go
then this quadrilateral those two has it
has the side BC the side BC parallel to
the side ad so set of one pair of
opposite rights those two parallel here
again as I hope ahead Oh slogan was
quadrilateral co-op ka-ho trapezium yes
it can become if we call it trapezoid so
quadrilateral that has one pair of
opposite sides paddle that is called as
trapezium and those are this this is how
we draw a trapezium now our point is cut
over those two also the each of these
figures below those so they are all
trapeziums qqk up they okay you can see
that those are these two sides this side
and this side are parallel this side and
this side of parallel this side on this
side of parallel and also it is also
equal to understand key the other two
sides you can have em carry only one
pair of opposite sides parallel so job
in the other pair head that should not
be banned well right so you loosely
paper that is not parallel so those are
in quadrilateral scope we call them
trapezium now we are going to take a
look at the next time so now those are
you have a hamari this was our third
type so the third type does though now
this type of quadrilateral is called a
parallelogram
parallelogram so parallel
M is a quadrilateral that has both sides
of both pairs of opposite sides parallel
trapezium a trapezoid meant we have seen
only one side one pair of opposite sides
parallel but parallelogram Agosto it is
such a quadrilateral that has both pairs
of opposite sides parallel Somali yoga
again if this one is a b c d a Gurria
hamari a b c d a quadrilateral here then
the slope if we have manly g a b if we
have AV parallel to a be jaha parallel
to CD if we have a be parallel to CD
first condition and second condition
have bc parallel to ad BC parallel to ad
other those two if these two conditions
are met then we will say this
quadrilateral ABCD is a parallelogram so
this is what is called as a
parallelogram telling us so let us
continue to move forward now also you
recall this shape and AB there we go so
this is what we call as a rectangle this
was our fourth this was our fourth shape
and of kamala middle so this is called
as a rectangle
now this weight unit is up they forget
about rectangle rectangle is also a
parallelogram because a side and a side
if we write this as ABCD if it is a like
if it's a parallelogram or if it is a
quadrilateral ABCD up there with also jo
AAP here that is parallel to CD and BC
is parallel to ad so this is a
parallelogram so rectangle is a
parallelogram and you have because of
the only difference is one of its angle
is 90 degrees so other app Quito a angle
is osco will be a Kangol a guru scheme
measure 90 degree ho T here so then if
you have a parallelogram ABCD with one
angle as 90 degree so also a
behave rectangle so it's a parallelogram
that has one angle 90 degrees so to
start such okay QR great angle 90 degree
hona say why it is like this because
those are equal keys are great angle 90
degree head and this is also 90 degrees
why q those are negative we talked about
parallel lines right muhabba graphic
transverse a little then the the angle
formed interior angle formed on the same
side of transversal they're
supplementary that is some of them are
90 degree so you happy no swaps or sakte
ho key BC and AD are parallel lines and
a B is a transversal so these two
together will be 180 degree again a 90
header permits this is also 90 degree so
similarly those that you you will find
out this is also 90 degree this is also
90 degree so I am catalyst agaric
parallelogram a1 angle 90 degree Agora
poet nahi information DJ here then we
know we are talking about a rectangle
right naturally so let us not take a
look at our next type which is our fifth
type so this a head rhombus
so rhombus is a parallelogram that has
all sides equal so parallelogram those
become alumina basically again a be till
in let us write this a b c d right so we
know that I'm a malum Han ki jo a be
head that actually is parallel to CD a
my malam here
joby see here that is also parallel to
ad so by knowing these two we know ABCD
is a parallelogram but those is Callaham
a abd go ahead key all sides are equal
that is a B is equal to BC is equal to
CD is equal to ad so in addition to
those two the fact that AV is parallel
to CD and BC is parallel to ad how may a
BD k Hecky all these sides they are all
of equal length so that
Jota Heather so then this shape or this
quadrilateral will be called a rhombus
now those are we are gonna take a look
at the next quadrilateral next
quadrilateral goes to head is a square
now from all over the circle we take a
parallelogram that has all sides equal
and one angle is 90 degrees so a Cassie
quadrille it's it's such a parallelogram
errupted
Afghan separates such a quadrilateral so
happy you have a b c d ad is parallel to
C the BC is parallel to ad and those two
a B BC CD da they are all equal and you
have an angle 90 degree again as I has
also then you know this shape or this
quadrilateral is called a square and
those are we are going to talk about a
final type of quadrilateral
so go ahead also kite kite and ipython
those though and the reason this shape
is called quadrilateral is called kite
is because Oscar a quadrilateral whose
adjacent sides are equal adjacent sides
are equal so up come a level is the
adjacent sides come up let her pass pass
key side so shall I say let us write
this as a b c d so you have those two
what is given is that a b is equal to ad
and C B is equal to C D so the say a B
is equal to ad or your BC here that is
equal to CD
so if shape of the study coordinator
kite so this kind of quadrilateral is
called a kite but happens also it is
important to know that this particular
shape is not a parallelogram because you
have because the ad is not parallel to
CD and AD is not parallel to BC so you
a this is a quadrilateral it is also not
a trapezium you get wavy one pair of
sides parallel here only conditions
Ohama maluma is that adjacent sides that
is passed past either side here they are
equal so a B case at a D equal and BC
case at CD so these two are equal either
as a hota head also if the if this is
the only thing that we know then we call
that quadrilateral a kite Yannick
ipython so yeah those the hamari this I
think was I believe this was our seventh
and the last shape that we wanted to
discuss say what those if you want to
quickly go back and take a look at the
shapes that we had here right suddenly
Ricardo stopped yeh actually see this
one was it had two sides parallel this
side was parallel to this side so yet
when Vagos the hamari trapezium right
trapezium now for this figure those that
we have both opposite sides are parallel
both pairs this is parallel to this this
is parallel to this jump both pairs of
opposite sides parallel to those oh say
we call it parallelogram we call it
parallelogram right then those that we
saw key it's a parallelogram T here and
it has one angle 90 degree again as a
Hokkaido so this is called as a
rectangle right then those that we saw
parallelogram jabarut sides are parallel
but in addition to that opposite sides
or all the sides are also equal but let
this side is equal to this side is equal
to this side is equal to this side so
there as a hotel hostel we call that
parallelogram we call it rhombus we call
it rhombus busca bothersome Malaika
basically a parallelogram where all
sides are equal and you have one angle
90 degree who say we call it square
and finally this our last type of
quadrilateral jaha pay we have adjacent
sides equal and Hammett who EP side kiss
except parallel in here after as a hotel
hostel we call that a quadrilateral we
call it a kind so those are these where
the different kinds of quadrilaterals we
wanted to discuss in this presentation
so those are hopefully are following us
along a be those are going forward we
are going to start learning about
different things about quadrilateral and
we are going to also focus a lot about
parallelograms so that's the hopefully
you are following us along and like we
always say get up game and make it so
Val here quick question that you want to
find out please don't hesitate to let us
know up basic how may send us a comment
and we will be very happy to answer
those questions for you at his
presentation my hellos are gonna be some
familiar topic we should create anyone
presentation from rising pearl hum apke
host aqua destroy first though I've
Kamala may we have just started a brand

the heroes though so we first join a b
then b C then C D and D a whose order
may then we get a we get a closed figure
like this which has four sides a b b c c
d da and char corner a b c d and four
angles angle a angle B angle C and angle
D so yeah those times I close figure
Milty here this is what we call as
quadrilateral ABCD and you say we write
it like this quadrilateral a b c d so
those and these are the unique things
about quadrilateral four corners four
sides four angles so adds those that we
