Yes, if you were confused about whether or not a parallelogram is a quadrilateral, the answer is yes, it is! 6.4.2: Use properties of rectangles, rhombuses, and squares to solve problems. Because it has four right angles, a square is also a rectangle. Property 3:  Diagonals bisect each other & are perpendicular, Property 4:  Diagonals are all congruent & bisect vertices, Property 5:  Supplementary Consecutive angles, Prove that diagonals of a Rectangle Are of Equal Length, PQRS is a rectangle with PR and QS as its diagonal, Since PQRS is a rectangle, ∠P = 90° QR=PS, Δ PQS = Δ QPR (by law of Side Angle Side postulate), PR= QS (Corresponding Parts of Congruent Triangle). 6-4 Practice A Properties of Special Parallelograms Match each figure with the letter of one of the vocabulary terms. If they are not congruent, the shape can not be called a parallelogram. We will call these the special properties of the rhombus. A: The six properties of a parallelogram are:(i) Opposite sides are parallel and congruent. So, a parallelogram is a quadrilateral with opposite sides parallel and therefore the opposite angles equal.
