The coordinates of quadrilateral ABCD are located at A (-2, 3), B (4, 5), C (6, -1) and D (0, -3). a) Using coordinate geometry methods, show that the diagonals bisect each other.

b) Using coordinate geometry methods, show that the diagonals are perpendicular.

c) Using coordinate geometry methods, show that all four sides are congruent.

d) Using coordinate geometry methods, show that the diagonals are congruent.

e) Based only upon the information shown in parts a, b, c and d, what name can be given to this quadrilateral? (Parallelogram, Square, Rectangle or Rhombus?)
