www.benjamin-mills.comOpposite angles in a cyclic quadrilateral We want to prove the sum of opposite angles of a cyclic quadrilateral is 180°. a b Step 1: Create the problem Draw a circle and its centre, choose four points on its circumference and connect them with lines to form a cyclic quadrilateral. Label two opposite angles – I chose a and b.
