equilateral triangle

In classifying triangles by side length, we can have three types of triangles: equilateral, isosceles, and scalene triangles.

An equilateral triangle is a triangle in which all three sides have the same length.

An isosceles triangle is a triangle that has two sides of equal length.

A scalene triangle is a triangle with all sides of different lengths.

The triangle shown has three sides of equal length, each \(12\) cm. Thus, it is an equilateral triangle.
