Sum of opposites angles of a cyclic quadrilateral is 180° | Easy Method | Central Angle Theorem
We’re required to prove that the sum of opposite angles of a cyclic quadrilateral is 180°. For this, we use Central Angle Theorem. Central Angle Theorem Angle subtended by an arc at the center is double the angle subtended by it on remaining part of the circle. Proof: Consider a Centre of the circle, Say…
