L9 : Numerical-2 - Intro to Euclid Geometry, Maths, Class 9 Video Lecture

hello friends this video on introduction
to nuclear geometry part 9 is brought to
you by exam viacom no more fear from
exam so let's take some numerical norm
let's consider the following say in
there exists a pair of straight line
that are Olivia equidistance from one
another is this thick minute are a
consequence false positive yes saying
there exists a pair of straight lines
that are everywhere in Krita system if
this level is same same if these are
parallel that means then they are always
English to push this this is the
statement we have to say that is this is
a direct consequence is costly so fifth
postulate let's see so let's see as per
our place where axiom that is nothing
but part of form it operates with
postulate so if there is a line L and
there is a point P and this point pi is
not on the line then by playfair's axiom
there is a unique line m that passed be
valid like L in possibility so these two
lines are really very critical so they
are parallel to their likeness okay so
the policia
this statement is actually a consequence
statement say that there exists a pair
of mine that are equal distance from
that means they exist or they exist a
parallel line it's a there exists a
straight like way of stating they are
not saying paralyzes the saying that
there exist a pair of straight line
where the distance between
these points are seen that means they
are saying that there exist come set up
nice and it is a direct consequence of
postulate paint because as per the may
apply here axiom this distance being you
can draw a line parallel to L caused it
to be and they can have only one line
okay how do you rewrite Euclid's fifth
postulate so that it will be easy to
understand easier easiest way I can say
that two distinct intersecting lines
cannot be parallel to say night we have
seen steady state
there are two lines Ln M L is parallel
to L - they can say that M will not be
parallel to illness if they are okay
let's take molasses up and does the
Euclid's fifth postulate imply the
existence of life yes Ashley which make
you sleep pasta dare to lie another line
angle 1 and angle 2 L 1 plus angle 2 is
less than Murray 88 hey but if angle 1
the single 2 is equal to Y we do not
need so it allowed me that means they're
parallel correct so does the parallel
line is actually when new blades fifth
postulate imply the existence of
parallel lines ok let's do a quick
summary though Euclid's define a point
lying plain your definitions were not
accepted by the mathematicians and they
are considered in define because we use
some term which we are not defined to
define this axioms or postulates the
assumptions they are obvious universal
axioms are general and postulates are
more specific intimately turns our
statement we shall prove and they are
proved using definition axioms
previously theorems and also deductive
reasoning to either an equivalent
version of grades fifth postulate we
have seen first was for every line L n
for every point P that is not like L
they existed might help the listening
like M which is passing through point P
and paddled well there's a plate here
postulate easier world world they are to
listing intersecting lines they cannot
be passed into lines they cannot even
see em protecting
hell you can be parallel to a less and
and for this for every line L
the mr. point B which is not my health
and it exists in unique like L it is
passing to this point B and thank you
