Hint: draw radii and use the properties of isosceles triangles and the fact that the angles of a triangle add up to 180.

Let there is a circle with centre O and radius R. AB is an arc and Let P and Q are point on the same segment. Now angle APB = 1/2 angle AOB and angle AQB is also 1/2 angle AOB(because angle subtended by an arc on the centre is twice the angle subtended by it in its corresponding alternate segment). hence angle APB = angle AQB.

each angle is half the angle subtended at the centre and the angle subtended at the centre is one and the same angle.so they are equal.a figure would have made it abundantly clearer
