# 13 Fun Examples of Equilateral Triangle in Real Life

You might have seen an equilateral triangle in your geometry class but have you ever thought about the equilateral triangle in real life? Triangle identification is important to recognize equilateral triangles properly. Several objects have the shape of an equilateral triangle. Equilateral triangles can be found in many places in the world around us, from traffic signs on the street to the toppings on a pizza. In this article, we will explore some examples of equilateral triangles in real life. So, get ready to discover some fascinating ways that equilateral triangles are used around us!

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.
