In the two trapeziums below, we have drawn triangles by joining the vertices of one of the non-parallel sides to the midpoint of the opposite side. WebSep 10, 2024 · So both pairs of opposites angles are equal and must be 180°. Hence we have a cyclic quadrilateral. The next step is to consider the trapezium ABCD. As F and E are both midpoints, FE is parallel to AB and also to CD. Angles CDA = EFQ and BCD = PEQ so CDQP is also cyclic. It also easy to show ABPQ is cyclic.
A right trapezoid (also called right-angled trapezoid) has two adjacent right angles. Right trapezoids are used in the trapezoidal rule for estimating areas under a curve.
