Determine whether Quadrilateral ABCD below is a parallelogram by showing diagonals bisect each 7. When you said that none of the above was correct, I think what you were referring to was intersecting diagonals, in … The rectangle has the following properties: All the properties of a parallelogram apply (the ones that matter here are parallel sides, opposite sides are congruent, and diagonals bisect each other). Answers: 1 on a question: Which description does not guarantee that a quadrilateral is a rectangle? The two diagonals of a parallelogram bisect each other, and the opposite sides and angles of any parallelogram are congruent. Rectangle. 5 years ago.
