## Introduction to Equilateral Triangle: Definition and Properties

When the three sides of a triangle are equal in length then it is called an **equilateral triangle**. This also means that the three angles are equal to 60 degrees.

The word “**equilateral**” is a Latin word. In Latin, “**equi**” means equal, and “**latus**” means side. Its symmetrical properties make it useful in mathematics, geometry, and daily life.

**Perimeter**: As the three sides are equal, the perimeter will be the summation of the ** 3** sides.

Suppose, you have three sides equal to “a”. Then the **Perimeter = 3a**.

**Area**: If the three sides of an equilateral triangle are “**a**”. Then the area of the triangle is =**√3∕4a².**
