Prove that a diameter of a circle which bisects a chord of the circle also bisects the angle subtended by the chord at the centre of the circle.

Prove that a diameter of a circle which bisects a chord of the circle, also bisects the angles subtended by the chord at the centre of the circle.

The chord of a circle is equal to its radius, find the angle subtended by this chord at the centre.

If the length of a chord of a circle of diameter 40 cm is 20 cm , what is the angle subtended by the chord at the centre of the circle ?

Prove that, if a diameter of a circle bisects two chords of the circle then those two chords are parallel to each other.

If the length of a chord of a circle is equal to that of the radius of the circle , then the angle subtended , in radians , at the centre of the circle by the chord is

A diameter of a circle is a chord that ..... the centre of the circle.
