Crossed isosceles trapezoid

The crossed isosceles trapezoid is a crossed trapezoid with a single symmetry axis. Equivalently, it is a crossed trapezoid with the same leg lengths and base angles. It has 1 top edge, 2 intersecting side edges of the same length, and 1 base edge. It has 2 pairs of identical vertices, as the angles at either end of the bases are the same.
