A square is different from a rectangle because all four sides of a square are the same length, while a rectangle has opposite sides that are equal, but not all four sides have to be the same. Both a square and a rectangle have four right angles (90 degrees), but only the square has four equal sides. So, every square is a rectangle, but not every rectangle is a square because of the side lengths.
