(b) You may use the grid below to help you answer this question.
          The points (2, 1), (4, 3), (3, 1) and (p, q) form a quadrilateral.
          This quadrilateral has rotational symmetry order 1 and one line of symmetry.
(ii) Given that p and q are integers, find two other possible positions of (p, q).
