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.
It is any triangle that has two sides the same length. If all three sides are the same length it is called an equilateral triangle. 1  The unequal side of an isosceles triangle is usually referred to as the 'base' of the triangle.  The base angles of an isosceles triangle are always equal.
