“If ABCD is a square with points A(2 3) B(-2 2) C(-1 -2) what are the coordinates of point D?”

"If ABCD is a square with points A(2 3) B(-2 2) C(-1 -2) what are the coordinates of point D?"
Answer: "(3 -1)"

"Given three vertices of a square the fourth point D is calculated to be (3 -1). 'Coordinates of point D' refer to the location of the missing vertex."
