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.
