Since you didn't specify the coordinates of the vertices of quadrilateral ABCD, this quadrilateral could be any quadrilateral. Since it is NOT true that all quadrilaterals are parallelograms, it is quite possible that ABCD is indeed a quadrilateral that is not a parallelogram. Hence, what you ask is impossible. Re-post your question with ALL of the pertinent information.
