Question

Draw a pair of tangents to a cirde of radius 4 cm, which are incined to each other at an angle of 60​

Answer 1

Step 1 : Draw a circle of radius 4 cm and with centre as O.

Step 2 : Take a point A on the circumference of the circle and join OA. Draw a perpendicular to OA at point A.

Step 3 : Draw a radius OB, making an angle of 120
