Equilateral Triangle
Equilateral Triangle is a triangle with all three sides and all three angles equal. As we know a triangle has three angles and three sides, thus in an equilateral triangle all three sides and all three angles are equal. Hence, it is also called a equiangular triangle.
Where each angle measures 60 degrees, similar to other types of triangles. The word equilateral is made of two words “equi” and “lateral” where equi means equal and lateral means side. Thus equilateral triangle means a triangle with equal sides. In this article, we learn about equilateral triangles, their properties of equilateral triangle, their formulas of equilateral triangle, and others in detail.
