SUMMARY Theorem 1: The perpendicular from the centre of a circle to a chord bisects the chord. Theorem 2: There is one and only one circle passing through three given non-collinear points. Theorem 3: the 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. Theorem 4: Angles in same segment of a circle are equal. Theorem 5: angle in the semicircle is a right angle. Theorem 6: the sum of either pair of opposite angles of a cyclic quadrilateral is 180°. Theorem 7: Equal chords of a circle (or of congruent circles) are equidistant from the centre (or centers). Theorem 8: A tangent to a circle is perpendicular to the radius through the point of contact. Theorem 9: Lengths of two tangents drawn from an external point to a circle are equal.
