Is this an equilateral, an isosceles, or a scalene triangle?

In this question, we’re shown a triangle, and we have to identify which type of triangle it is. Is this an equilateral triangle? An equilateral has three equal sides. All of its sides are equal in length. The given triangle has two sides equal in length. So, we know it’s not an equilateral triangle. Is it an isosceles triangle? We know that isosceles triangles have two sides which are equal in length. The given triangle is an isosceles triangle. We know it’s not a scalene triangle because scalene triangles have three sides all different in length. This triangle is an isosceles triangle. We know this because two of its sides are equal in length.
