Since you have 5 more to do, there is a little trick that works sometimes: If the rectangle has SIDES PARALLEL to the axes, AND If the points are given in order, then there is an easy trick:|dw:1433170359815:dw| You can cancel identical coordinates of ADJACENT points. What's left is the fourth vertex.
