Q6 of 12 Page 242

⨀ (P, 4) is given. Draw a pair of tangents through A which is in the exterior of ⨀(P, 4) such that measure of an angle between the tangents is 60° .

Angle between the tangents =60°


We first find the angle between the radius.


Angle between radius + Angle between tangents =180°


⇒ Angle between radius = 180-60=120°


Steps of Construction:


1. Draw a circle of radius 4cm and center P.


2. Draw a radius on the circle. Draw another radius making 120° with this radius.



3. From the points on the circumference on the circle, draw perpendiculars to these radius.



4. They intersect each other at one point.
