Question

Three vertices of a parallelogram are (4,7), (7,7), and (9,2). Where should the next points be to graph a parallelogram.

Answer 1

Plotting the points into the rectangular coordinate system :

The next point should be in the same level as the point (9, 2)

The measurement of top and bottom side must be the same.

By counting, the measurement of top is 3, so the bottom must be 3 also.

Counting 3 units to the left of (9, 2), we will get the point (6, 2)

The answer is (6, 2)
