A, B, P and Q are points on the circumference of a circle with centre O. If angle AQB is , then which of the following can be the value of angle APB?

60^o

We know that,

Angles made by same chord on the circumference of the circle are equal.

Angle AQB = 60°.

Angle AQB = 60° makes by chord AB on the circumference of the circle , also angle APQ makes by the same chord AB on the circumference of the circle.

Angle AQB = angle APQ = 60°
