The parpendicular drawn on radius at the end point of radius of a circle will be a tangent to the circle at the end point of radius.

Draw a line segment XY of length 8 cm and taking XY as the diameter, draw a circle . Then construct two tangents to that circle at the points X and Y. Also find the relation between the two tangents.

Two circles touch each other extenally at the point A. A common tangent drawn to two circles at the point A is a "______" common tangent. (direct/ transverse)

P and Q are two points ona circle with centre at O. R is a point on the minor arc of the circle, between the points P and Q. The tangents to the circle at the points P and Q meet each other at the points S. If anglePSQ =20^@ , then anglePRQ =
