Tests for Parallelograms• If one pair of opposite sides are parallel and
congruent, then it is a parallelogram• If both pairs of opposite sides are parallel, then
it is a parallelogram• If both pairs of opposite sides are congruent,
then it is a parallelogram• If both pairs of opposite angles are congruent,
then it is a parallelogram• If diagonals bisect each other, then it is a
parallelogram

Tests for Rectangles
• If a quadrilateral has four right angles, then it is a rectangle
• If a parallelogram has congruent diagonals, then it is a rectangle

Properties for a RhombusBoth pairs of opposite sides are parallel and congruentDiagonals bisect each otherOpposite angles are congruentConsecutive angles are supplementaryDiagonals intersect at 90 degree anglesEach diagonal bisects opposite anglesAll sides are congruent

Tests for Rhombi
• If the diagonals of a parallelogram are perpendicular, then it is a rhombus

Tests for Squares
• If a quadrilateral is a rectangle and a rhombus, then it is a square
