Explain: A square is always a rectangle, but a rectangle is not a square.
To be a rectangle, a shape needs 2 pairs of parallel sides and 4 right angles, a square has both of those so it is also a rectangle.
A square also needs to have 4 equal sides, a rectangle does not have 4 equal sides, so a rectangle is not a square.
