Draw a pair of tangents to a circle of radius 4.5 cm, which are inclined to each other at an angle of 45°.
. Draw a circle with centre O and radius 4.5 cm.
. Draw any diameter AOB of the circle.
. Construct BOC = 45º such that radius OC cuts the circle at C.
. 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.
