Equilateral triangles are a subset of isoceles triangles. In other words, a triangle is isoceles if it has at least two equal sides...not EXACTLY two.

This was a good post. Even i initially marked this answer as E. But yes if a triangle is an equilateral triangle, then the triangle has to be a isosceles triangle.

Good Post...
