### What Is Rhombus?

A Rhombus is quadrilateral with opposite sides parallel and all sides equal length.A
rhombus whose angles are all right angles is called a square.A rhombus(or dimond)is
a parallelogram with all 4 sides of equal length.

### What Are Calculation Option Available In Rhombus?

Select which value you are providing (Corner Angles(A,B,C,D) , Side Length(a), Long
Diagonal(p), Short Diagonal(q), Height(h), Perimeter(p), Area(K) ), input value
and Click on Compute.

A Rhombus is quadrilateral with opposite sides parallel and all sides of equal length .We can get the value of all corner angles (A,B,C,D) , Side Length(a) , Long Diagonal(p) , Short Diagonal(q) , Height(h) , Perimeter(P) , Area(K) by using following formula :

** Corner Angles A,B,C,D :**
A = C

B = D

A + B = 180^{o}

Where

A, B, C, D = Corner Angles

**Long Diagonal:**
p = a√(2+2cos(A))

Where

p = Long diagonal

a = side

A = corner angle

**Short Diagonal:**
q = a√(2-2cos(A))

Where

q = Short diagonal

a = side

A = corner angle

**Perimeter:**
P = 4a

Where

P = Perimeter

a = side

**Area:**
K = ah

Where

K = Area

a = side

h = Height

**Height :**
h = asin(A)

Where

h = Height

a = side

A = corner angle

### How to use Rhombus Calculator?
