Hi, cupcake_sarahk

You want to verify it is a parallelogram by using the distance formula. In a parallelogram, opposite sides will be equal to one another.

Once you find the distance, you can put it in a ratio. A Rhombus has equal opposite sides. If the ratio of the opposite sides are equal, then it is a Rhombus.
