Prove that an isosceles trapezium is cyclic
Webb27 dec. 2015 · Problem : We need to prove that any isosceles trapezium is con-cyclic. Solution :Here’s an isosceles trapezium with sides PQ and RS are parallel and PS = QR. A quadrilateral is cyclic if it’s opposite angles are supplementary (i.e. they add up to 180˚). So , we need to prove that QPS + QRS = 180˚ and PSR + PQR = 180˚. Webb18 juni 2015 · Prove that Q U A D is an isosceles trapezoid. ∗. I first managed to prove the theorem drawing a line through U parallel to A D ¯ , then extending Q U ¯ and A D ¯ and working with proportions. Needless to say, the proof got a bit involved. Later I designed a different proof: Suppose U A ¯ and D Q ¯ are not parallel; then they meet in a ...
