The slopes of parallel lines are equal. So if the line through two adjacent vertices has a slope equal to the line through the other two vertices, then you at least have a trapezoid. Then if the other pair of lines also have equal slopes, you have a parallelogram.

The slope formula is:

where

and

are the coordinates of the given points.

You have to use this formula four times.
