An angle subtended by an arc at the centre is double the angle subtended by it at any point on the remaining part of the circle.In the figure,  AB is the diameter of the circle, find the value of  ∠ACD

A chord of a circle is equal to the radius of the circle. Find the angle subtended by the chord at a point on the major arc.

(Prove) The angle subtended by an arc at the center is double the angle subtended by it at anypoint on the remaining part of the circle.

The circle below has center O, and its radius is 6cm. Given that =m∠AOB50°, find the length of the minor arc AB.Give an exact answer in terms of π, and be sure to include the correct unit in your answer.
