Quadrilateral ABCD is not a rhombus because opposite sides are parallel but the four sides do not all have the same length. B. Quadrilateral ABCD is a rhombus because opposite sides are parallel and all four sides have the same length. C. Quadrilateral ABCD is not a rhombus because there are no pairs of parallel sides. D. Quadrilateral ABCD is not a rhombus because there is only one pair of opposite sides that are parallel.25 points for the answer
