WebbProve that an isosceles trapezium is always cyclic. Solution Given : A trapezium ABCD in which AB ∥DC and AD=BC To prove: ABCD is a cyclic quadrilateral Construction : Draw … Opposite angles are supplementary, which in turn implies that isosceles trapezoids are cyclic quadrilaterals. The diagonals divide each other into segments with lengths that are pairwise equal; in terms of the picture below, AE = DE, BE = CE (and AE ≠ CE if one wishes to exclude rectangles). Angles [ edit] Visa mer In Euclidean geometry, an isosceles trapezoid (isosceles trapezium in British English) is a convex quadrilateral with a line of symmetry bisecting one pair of opposite sides. It is a special case of a trapezoid. Alternatively, it can … Visa mer If a quadrilateral is known to be a trapezoid, it is not sufficient just to check that the legs have the same length in order to know that it is an isosceles trapezoid, since a rhombus is a special case of a trapezoid with legs of equal length, but is not an isosceles trapezoid … Visa mer The diagonals of an isosceles trapezoid have the same length; that is, every isosceles trapezoid is an equidiagonal quadrilateral. Moreover, the diagonals divide each other in the same proportions. As pictured, the diagonals AC and BD have the same length (AC … Visa mer The radius in the circumscribed circle is given by In a Visa mer Rectangles and squares are usually considered to be special cases of isosceles trapezoids though some sources would exclude them. Another special case … Visa mer In an isosceles trapezoid, the base angles have the same measure pairwise. In the picture below, angles ∠ABC and ∠DCB are obtuse angles of the same measure, while angles ∠BAD and … Visa mer The area of an isosceles (or any) trapezoid is equal to the average of the lengths of the base and top (the parallel sides) times the height. In the adjacent diagram, if we write AD = a, and BC = b, and the height h is the length of a line segment between AD and BC that is … Visa mer
