# Rhomboid

In a rhomboid, these formulas hold:

a = c and b = d

alpha = gamma and beta = delta

Area = side * height on side

Further measurements are easily gotten by dividing the rhomboid into two triangles.

Typical for a rhomboid is that opposing sides are parallel. Furthermore, opposing sides have the same length, and opposing angles are equal.

In most cases, a rhomboid is uniquely defined by three values, e.g. by two sides and an angle.

Therefore, many triangle calculation rules can give rhomboid calculation rules. For example, area A = side * height because this is twice the area formula of a triangle.

For further information, move the mouse over one of the words below, and the corresponding part is marked on the rhomboid.
