In this video, students learn aplication of Circles theorems (Several Theorems) and sample problems relating circles and associated angles.

Circles theorem 1. A circle is the collection of all points in a plane, which are equidistant from a fixed point in the plane.

Circles theorem 2. Equal chords of a circle (or of congruent circles) subtend equal angles at the centre.

Circles theorem 3. If the angles subtended by two chords of a circle (or of congruent circles) at the centre(corresponding centres) are equal, the chords are equal.
