Question

What are three ways a rectangle and a square are alike

Answer 1

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.

-- 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).
