Use this simple geometry calculator tool to calculate area of a rhombus. Rhombus is a special type of parallelogram, all properties of parallelograms apply to rhombi. If a triangle is rhombi, Opposite angles are congruent. Any pair of consecutive angles are supplementary.
Definition of a rhombus
A rhombus is a quadrilateral with all sides equal.
Properties of a rhombus:
All properties of parallelograms apply to rhombi.
The diagonals of a rhombus bisect each vertex angle.
The diagonals of a rhombus bisect each other at right angles.
The opposite angles of a rhombus are equal.
The opposite sides of a rhombus are parallel.
Formula:
A = b × h
A = ½ × [d1 × d2]
A - the area of a rhombus
a - is the altitude (height)
d1, d2 - the length of diagonals
