Draw a pair of tangents to a circle of radius 13.2 cm which are inclined to each other at an angle of 70°.
Sum of angles between the tangents and corresponding radius is 180°.
As the angle between the tangents is 70° so the angle between the radius will be (180° - 70°) =110°.
Steps of Construction:
1. Draw a circle with center O and radius 2.4cm.
2. Draw a radius OA of this circle.
3. Draw another radius OB which is 110° to OA.
4. Extend OA such that OA=AP.
5. Draw a perpendicular bisector of OP.
6. Extend OB such that OB=OQ.
7. Draw a perpendicular bisector of OQ.
8. The two perpendicular bisectors meet at T.
9. ∠ATB=70°.
