Steps of Construction
Step 1: Draw a circle with center O and radius 3c m.
Step 2: Draw any diameter AOB of the circle.
Step 3: Construct ∠BOC = 60° such that radius OC cuts the circle at C.
Step 4: Draw \(AM \perp AB\) and \(CN \perp OC.\) Suppose AM and CN intersect each other at P.
Here, AP and CP are the pair of tangents to the circle inclined to each other at an angle of 60°.
