Question
Draw a pair of tangents to a circle of radius 4.5 cm, which are inclined to each other at an angle of 45°.
Solution
Steps of Construction
Step 1. Draw a circle with centre O and radius 4.5 cm.
Step 2. Draw any diameter AOB of the circle.
Step 3. Construct ∠BOC = 45º such that radius OC cuts the circle at C.
Step 4. Draw AM ⊥ AB and CN ⊥ 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 45º.
