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.
A triangle with all sides equal is called equilateral, a triangle with two sides equal is called isosceles, and a triangle with all sides a different length is called scalene. A triangle can be simultaneously right and isosceles, in which case it is known as an isosceles right triangle.f a line is drawn parallel to one side of a triangle so that it intersects the other two sides, it divides them proportionally, i.e., (14). (Jurgensen 1963, p. 251). In other words, a line parallel to a side of a triangle cutting the other two sides creates a triangle similar to the first.
