Answer:

D(6, 3)

Step-by-step explanation:

The diagonals of a rectangle bisect each other, so the midpoint of AC is the same as the midpoint of BD. This means ...

(A +C)/2 = (B +D)/2 . . . . the midpoints are the same

A +C = B +D . . . . . . . . . multiply by 2

D = A +C -B = (2+5-2, 1+5-3) . . . . . solve for D, substitute given coordinates

D = (6, 3)
