<P> In an isosceles triangle that has exactly two equal sides , the equal sides are called legs and the third side is called the base . The angle included by the legs is called the vertex angle and the angles that have the base as one of their sides are called the base angles . The vertex opposite the base is called the apex . In the equilateral triangle case , since all sides are equal , any side can be called the base . </P>
