Parallelogram 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 °.

Parallelogram circumference

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

U=2a+2b

Parallelogram area

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

F=absinα

Length of the parallelogram diagonals

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

d1=a2+b2-2abcosα

d2=a2+b2+2abcosα
