Rhombus Calculator

Calculations in a rhombus. A rhombus is a quadrilateral with four sides of equal length. Opposite sides are parallel. Enter the side length and one angle and choose the number of decimal places. Then click Calculate. Please enter angles in degrees, here you can convert angle units.


Euclid Side length (a): Rhombus
First angle (α):
Second angle (β):
Perimeter (p):
Area (A):
First diagonal (e):
Second diagonal (f):
Incircle radius (ri):
Height (h):
Round to    decimal places.



Formulas:
β = 180° - α
p = 4 * a
A = a² * sin ( α )
e = 2 * a * cos ( α / 2 )
f = 2 * a * sin ( α / 2 )
ri = a / 2 * sin ( α )
h = A / a = a * sin ( α )

Side length, diagonal, perimeter, radius and height have the same unit (e.g. meter), the area has this unit squared (e.g. square meter).

Diagonals and median lines meet in one point, this is the incircle center and the centroid. To this, the rhombus is point symmetric and rotationally symmetric at a rotation of 180° or multiples of this. Furthermore, the rhombus is axially symmetric to the diagonals. The diagonals are identical with the bisecting lines. The lengths of the median lines are equal to the lengths of the according parallel sides.
