Quadrilateral (ABCD) has vertices A(1,0), B(5,0), C(7,2), and D(3,2). Use slope to prove that (ABCD) is a parallelogram

THIS IS VERY SAD and not characteristic of Richard C. THERE WAS NO AUDIO!! It was unclear which of the FIVE methods of proving that a quadralateral was used (opposite sides are parallel -- same slope). Then, to frustrate even a good student, corrections were made during the solution. I expect much more from a "Confidence-building Geometry tutor.
