Answer:
Explanation:
In order to be a rhombus all the sides have to be congruent (same length) Rectangles have right angles, and squares have to have both congruent sides and right angles. You can calculate length using a distance formula, or use a slope formula to calculate if the sides are perpendicular but a quick sketch of the graph (actually just the points) can show you the answer or where to start calculating if you have to show that work. This parallelogram is a rhombus also, but not a square or rectangle. See image.
