There are two possible answers.
Draw a grid and draw A and D; the answer(s) should become obvious to you.

Here is part of the complex plane. I have plotted point A. Plot point D, then figure out where B and C must go to make ABCD a square. As I said, there are two possibilities.

Algebraically, B = A ± i(D - A) and C = D ± i(D - A), where the sign is chosen the same way in the two equations.
