What's the answer to this: A square is always, never, or sometimes a parallelogram?

Answer by  amtcura66 (1340)

A square must always be a parallelogram or else it is not a square. A square is defined four sides that are all the same length. A square cannot exist otherwise. All squares are parallelograms but not all parallelograms are squares. The lengths of the sides do not matter as long as they are all equal.

Parallelograms are four sided shapes that have two pairs of parallel sides. So, by that definition, a square is always a parallelogram.
