There are many possible answers. Consider the following parallelograms:

The three vertices of the triangle will combine with any of (-1,2), (5,12) or (13,0) to make a parallelogram. To actually find the coordinates of the fourth vertex, "slide" the opposite side over and just add the x- and y-coordinates.
