Best ResponseYou've already chosen the best response.0To Prove this you need to show that angle A = angle C since the chords are equal, arc AB = arc CD angle A = arc BC/2 angle C = arc AD/2 arc BC = arc CD + arc BD arc AD = arc AB + arc BD using substitution you can show that: arc BC = arc AD, therefore showing that angle A = angle C
