Enter side length a and height h

Enter diagonals length


Rhombus - a diamond shaped geometrical figure, the Rhombus is defined by 4 walls of the same length. All rhombi are parallelograms, those with only right angles are squares. The word comes from the greek ῥόμβος (rhombos) that means “something that is spinning”.

Equation form:

a =√(p² +q²)
Perimeter = 4 * a
Area enclosed (A) = a * h = a² sinα = a² sinβ =p * q
Area(AI) of circle inscribed in rhombus with height h:
AI =π * h²
Area(AI) of circle inscribed in rhombus with diagonals p, q:
AI =π * p² * q²
4(p² + q²)
