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.
If we define an isosceles triangle as one in which strictly two sides are of equal length then, no, an equilateral triangle is not isosceles. On the other hand, if we define an isosceles triangle as one for which there exists a pair of sides of equal length then, yes, an equilateral triangle is isosceles.
