An isosceles triangle is a triangle with two congruent sides and congruent base angles. congruent means equal. No matter which direction the triangle's apex, or peak, points, it's an isosceles triangle if two of its sides are congruent. Note the hash marks that indicate congruency. Any sides or angles with the same number of hashes through them are congruent.
The easiest way to define an isosceles triangle is that it has two equal sides. In an isosceles triangle, we have two sides called the legs and the remaining side called the base. The angle located opposite the base is called the vertex. Sample A: The vertex angle B of isosceles triangle ABC is 120 degrees.
