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°.
