What are three ways a rectangle and a square are alike

- - Each has 4 sides.

- - Opposite sides of each are parallel.

- - Opposite sides of each have equal length.

- - Interior angles of each sum to 360 degrees.

- - Each is a special case of parallelogram.

- - Each has all interior angles equal.

- - Area of either one is (length) x (width).

Rectangles and squares are alike in that both have two pairs of parallel sides and four right angles. They are different because a square must have four equal sides lengths and a rectangle has two pairs of equal side lengths.
