  1. ...find the slope? I'm not sure what you don't understand here. I mean, the vertex coordinates are given on the diagram right? Then it's easy. Just find the slope on each side and if the slope on both sides are the same then that proved they're parallel and thus is a parallelogram.

    In case you don't know this, for two given coordinates (x1, y1) and (x2, y2), where x and y = any real number. To find the slope:

    m = (y2-y1)/(x2-x1)

    Note: it doesn't matter which coordinate you set as coordinate 1 or coordinate 2 as long as you are consistent with your selection.
