There are four methods that you can use to prove that a quadrilateral is a square. In the last three of these methods, you first have to prove (or be given) that the quadrilateral is a rectangle, rhombus, or both: If a quadrilateral has four congruent sides and four right angles, then it’s a square (reverse of the square definition).
