Question

Explain why a square must be a rectangle but a rectangle does not have to be a square

Answer 1

Because they all have four sides and that all i know lol

Answer 2

Answer:

A rectangle is any four sided shape that has four right angles; Therefore, since a square is a four sided shape that has four right angles and congruent (equal) sides, it always has to be a rectangle. However a rectangle does not always have congruent sides, so it is not necessarily a square.
