Based on the information given, can you determine that the quadrilateral must be a parallelogram? Explain.

Description of image: its square it looks like that's slanted a little bit. The top-left corner is (X), the top-right corner is (Y), the bottom-left corner is (W), and the bottom-right corner is (Z). There is a line going from X to Z and a line going from Y to W. So where the two lines make an intersection is (N). I hope I described the image good. If you need any more help with the picture please let me know.
