Jan 21, 2020 · A trapezoid is isosceles if and only if its diagonals are congruent. So if we can prove that the bases are parallel and the diagonals are congruent, then we know the quadrilateral is an isosceles trapezoid, as Cool Math accurately states.

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.
The defining trait of this special type of trapezoid is that the two non-parallel sides (XW and YZ below) are congruent.
2D. shape with four sides. There are six special quadrilaterals with different properties. Square. A square has four sides of equal length. It has four right angles (90°). The opposite sides...
An isosceles trapezoid has exactly one line of symmetry. It can be found by drawing a line through the midpoints of the two bases of our isosceles trapezoid. Use this isosceles trapezoid calculator to explore all the various properties of these particular trapezoids.

An isosceles trapezoid’s interior angles add up to 360 degrees. The non-parallel sides of an isosceles trapezoid are congruent. The median runs parallel to both bases, and its length is equal to the sum of the bases’ lengths. “Trapezium” is another name for a trapezoid.
