When given the information below, can you conclude that Quadrilateral WXYZ is a parallelogram? Why or why not?
Masja [62]

B) No, because opposite sides are not parallel

Step-by-step explanation:

Given this information, assume that quadrilateral WXYZ is a parallelogram then we expect;

Parallel sides to be : WX // YZ   and XY // WZ

Additionally, we know parallel sides have equal gradient thus;

The slope of side WX= slope of side YZ and the slope of side XY= that of side WZ

However, from the information given, m of WX= 1/3 and that of YZ is -3, thus the two sides are not parallel to each other but perpendicular to each other because the product of their slope equals -1.
