Question

The coordinates of three vertices of parallelogram ABCD are A(-3,-2), B(0,2), and C(2,2). What are the coordinates of vertex D?A. (1,2)B. (1,-2)C. (-1,2)D. (-1,-2)

Answer 1

Clearly, the horizontal distance between B and C is two units (to the right of B), therefore the point D is two units to the right of A, according to parallelogram definition. Now the C has to be translated 4 units down, after all of the processes you will obtain the answer.

Point D has coordinates (-1,-2).
