Quadrilateral ABCD is a rectangle. The coordinates of vertices A and B are A(−4, 4) and B(4, 0). Vertex C lies on the y-axis. What are the coordinates of vertices C and D? Complete the explanation. The coordinates of C are ( , ) To find the coordinates of D, use the fact that when moving from B to A the run is and the rise is . So moving from C to D, the run and rise must be the same. The coordinates of D are ( , ).
