Quadrilateral proofs.

Hence if a pair of opposite side of a quadrilateral is parallel and congruent then the quadrilateral is a parallelogram. 3. The diagonals of the parallelogram bisect each other.If a quadrilateral has all right angles and congruent sides, then it is a square. So both the original statement and its converse (switching the hypothesis and conclusion) are both true. Thus, we can combine it into an if and only if statement, It is a square if and only if it is a quadrilateral with all right angles and congruent sides.The quadrilateral is a parallelogram whose diagonals are perpendicular to each other.
