### What Is Equilateral Triangle?

The Triangle having all three sides equal in Length and also all three angles are of 60° is Equilateral Triangle . This Calculator will help us to find 4 Unknown variables by Providing only 1 variable value.

### What Are Calulation Option Available In Equilateral Triangle?

Select which value you are Providing (Side Length (a) , Perimeter (P) , SemiPerimeter (s) , Area (K) , Altitude (h) ) input value and Click on Calculate .

The Equilateral Triangle has equal side length and Angle.Using Equilateral Triangle Calculator we can get the value of Side Length (a) , Side Length (b) , Hypotenuse (c) , Area (K) , Perimeter (P) , SemiPerimeter (s) , Altitude (h) for Equilateral triangle. We can get the value of Four unknown variables only if values of one variables are known . By using following formula :

Perimeter:

P = 3a
Where
P = Perimeter
a = Side Length

Semi Perimeter :

s = 3a / 2
Where
s = Semi Perimeter
a = Side Length

Area of Equilateral Triangle:

K = (1/4)*3a2
Where
K = Area
a = Side Length

Altitude of Equilateral Triangle:

h = (1/2)*3a
where
h = Altitude
a = Side Length
