Trapeze properties

The opposite sides are the same. The opposite sides are parallel. The diagonals halve each other. Opposite angles are equal. Two adjacent angles together result 180 °.

Trapeze circumference

With the side length a = AB = CD und b = BC = DA result the circumference:


Trapeze area

With the side length a and b and the angle α is the area:


Length of the trapeze diagonals

With the side lengths a and b the length of the diagonals is given by:
