Quadrilateral Project1SquareQuadrilateral with four congruent sides and four right angles.Rectangle

Quadrilateral with four right angles, opposite sides that are congruent, and opposite sides that are parallel.RhombusQuadrilateral with all four sides congruent.ParallelogramQuadrilateral whose opposite sides are parallel (congruent), opposite angles are equal, any side can be a base, and the altitude is the perpendicular distance from the base to the opposite side. Trapezoid

Quadrilateral with only one pair of parallel sides. Isosceles TrapezoidTrapezoid in which the legs are congruent, both pairs of base angles are congruent and the diagonals are congruent.THE MATRIX!!!!!Haha, Just kidding.(: Here ya go.

If both pair of opposite angles of a quadrilateral are congruent, then the quadrilateral is a parallelogram. If the diagonals of a quadrilateral bisect each other, then the quadrilateral is a parallelogram.If one pair of opposite sides of a quadrilateral is both parallel and congruent, then the quadrilateral is a parallelogram.
