Question

Three vertices of a square are (–1, 2), (2, 2), and (2, -1). What is the fourth vertex of the square? A. (–1, –1) B. (–1, –2) C. (2, 1) D. (2, 1)

Answer 1

I would plot (roughly on a piece of paper), the 3 points
then look for where to put the 4th point so they make a square shape.

Answer 2

Thank you for your help :)
