Interactive trapeze

Move the points in the grafic or define the point coordinates in the numeric field.

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:

U=2a+2b

Trapeze area

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

F=absinα

Length of the trapeze diagonals

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

d1=a2+b2-2abcosα

d2=a2+b2+2abcosα
