FAQs on Draw Tangent to a Circle Video Lecture - Class 10
| 1. How do you draw a tangent to a circle? |  |
Ans. To draw a tangent to a circle, follow these steps:
1. Draw the circle with its center and radius marked.
2. From the center of the circle, draw a radius that intersects the circle at a point.
3. Place the compass at the point of intersection on the circle and draw an arc that intersects the circle at two points.
4. From the center of the circle, draw a radius to one of the points where the arc intersects the circle.
5. The line drawn from the center to the point of intersection is the tangent to the circle.
| 2. What is a tangent to a circle? | |
Ans. A tangent to a circle is a line that touches the circle at exactly one point, without intersecting the circle. The point where the tangent touches the circle is called the point of tangency. The tangent line is always perpendicular to the radius of the circle at the point of tangency.
| 3. How many tangents can be drawn to a circle from an external point? | |
Ans. From an external point, two tangents can be drawn to a circle. These tangents are equal in length and are symmetrically positioned with respect to the line segment connecting the external point to the center of the circle. The tangents will intersect the circle at two different points.
| 4. Can a tangent to a circle be drawn from an internal point? | |
Ans. No, a tangent cannot be drawn to a circle from an internal point. If a point is inside the circle, the line connecting the center of the circle to the point will intersect the circle at more than one point. The tangent, by definition, only touches the circle at one point without intersecting it.
| 5. What is the relationship between the radius of a circle and the tangent drawn to it? | |
Ans. The radius of a circle is always perpendicular to the tangent drawn to it at the point of tangency. This means that the radius and the tangent line are at a 90-degree angle to each other. The length of the tangent line is determined by the distance between the center of the circle and the point of tangency.

hello friends this video on construction
part 3 is brought to you by exam viacom
no merge via from exam before watching
this video please make sure that you
have watched part 1 and part 2
so let's not a tangent we were to draw
our tangent to a circle from a point
outside it so this is a point example so
let's first draw a circle with Center oh
this is my circle Center and this is my
point
extra point also from this we have to
draw Beijing the first point thing is
take a point P outside so thumbs you
already there so you name it as join P
Oh let's join this line view and bisect
it
if I see you to read oh when you take
from this point will take a compass down
like this same length then again from
this point you know like this now again
from this point will draw like this and
now from this point draw next correct so
the line joining these two will join
like this this line this point is
something which bisects P you wanted to
bisect any line what you know from this
point
you think on the bus then don't like
this this point you like this again from
this point you draw Commerce and like
this that's from this point you draw
like this you get these two points you
join to get this as the meter so you got
the midpoint and let M be the weak point
so it's it mean put this point and then
they meet them
let M be the main point of P now let M s
Center and Mo is radius its draws up ms
end that and ever as really is awesome
so we avoid the circle correct same
thing using a pulse like this you get a
circle now you've got to point like this
so this intersects at the other circle
at two points and let next hand this
point to white and let's name this Q and
ha correct now what you do is you will
join EQ and Br
so let's join Beekman here so we have
joined people here and now you see P Q
and P are required engines details PQ
and be very simple whatever though
just remember the steps circle point
outside it join this P o bisected now
from this point draws them now move it
close are going to meet this at 2 point
you join these two much that's it and
they are root angels where is it well
this formal steps thank you
