Why is a triangle and a square congruent?

Answer 1

congruent means that all the sides are the same length. the sides of a square have to be the same length or else it would be a rectangle. Not all triangles are congruent though. there are other types of triangles unlike the square, where there is only one type.

Answer 2

A triangle and a square cannot be congruent since a triangle has three sides and a square has four.
