An isosceles triangle has exactly two sides which are equal. (The word congruent usually applies to triangles, not sides.)
A congruent triangle has three sides, just like any other triangle. The term "congruent" in this context means that the lengths of the sides of the triangle are equal to each other. So, regardless of whether a triangle is congruent or not, it will always have three sides.
Equilateral, Isosceles and Scalene are three types of triangles classified based on how many congruent sides the triangle has.
