The coordinates of vertex D.
Answer to Problem 37PPS
The coordinates of point D are (1, -1).
Explanation of Solution
Given:
ABCD is a parallelogram with vertices:
Calculation:
The diagonals of a parallelogram bisect each other.
Both of the diagonals have the same mid-point.
Therefore, the mid-points of AC and BD coincide.
Hence,
Equate the abscissa and the ordinates:
Therefore, the coordinates of point D are (1, -1).
