Question by Pickle Dude: How can I find out if ABCD is a parallelogram with the distance formula?
A is (-5,-5)
B is (-2,4)
C is (6,4)
D is (3,-5)
Please use the distance formula to determine whether ABCD is a parallelogram or not. Please show me work so I can learn how to do this.

All parallelograms have opposite sides equal.
So simply show AB = CD AND BC = AD.
If both of these are correct, you have a parallelogram. If not, you don't.
