To draw a pair of tangents to a circle which are inclined to each other at an angle of 60°, it is required to draw tangents at endpoints of those two radii of the circle, the angle between them should be


Construction:

In the given figure:


OP and OQ are the tangents to the circle.



Now,


Sum of opposite angles = 180°


POQ + PRQ=180°


60° + θ=180°


θ=120°


Hence, the angle between them should be 120°.
