Right trapezoids are used in the trapezoidal rule for estimating areas under a curve.

The four pieces are usually one isosceles right triangle, two right trapezoids and an irregular shaped pentagon.

A right trapezoid (also called right-angled trapezoid) has two adjacent right angles.

A right trapezoid is a trapezoid that has two pairs of adjacent sides that are perpendicular.

Another difference is that in the dissection of the T, one of the triangles is usually elongated as a right trapezoid.

The Latin cross puzzle consists of a reassembling a five-piece dissection of the cross with three isosceles right triangles, one right trapezoids and an irregular shaped six-sized piece (see figure).

The crossed ladders problem is the problem of finding the distance between the parallel sides of a right trapezoid, given the diagonal lengths and the distance from the perpendicular leg to the diagonal intersection.

A year later, NBC unveiled a new logo that was identical to the Nebraska ETV logo, but for the blue coloring of the right trapezoid in the NBC logo.

The new NBC logo was virtually identical to the logo that Nebraska ETV had been using since 1974, with the only cosmetic difference between the two designs being that the right trapezoid of the NBC logo had blue coloring.
