Question

Three vertices of a parallelogram are shown in the figure below.

Give the coordinates of the fourth vertex.
(-5,-5)
(2,7)
(0, -3)

Answer 1

For it to be parallel, the point must follow the translation from (2,7) to that point similar to (0, -3) to (-5, -5) which is left 5 and down 2. So left 5 and down 2 for (2, 7) makes it (-3, 5)
