WebCircle theorem includes the concept of tangents, sectors, angles, the chord of a circle and proofs. A circle is the locus of all points in a plane which are equidistant from a fixed point. The fixed point is called the centre of the circle, and the constant distance between any point on the circle and its centre is called the radius.
