Given:
The vertices of the parallelogram are:
Calculation:
The diagonals of a parallelogram bisect each other and both diagonals have the same midpoint.
Let the fourth vertex be (a, b).
So, the vertices will be:
The parallelogram formed by points A, B, C and D, will have the midpoints of AC and BD coinciding.
Therefore,
