    If it's a square, all the sides are equal.

    plot the points. the length of AB is  √(4²+2²) = √20 = 2√5

    using x,y coordinates, the eq of the line thru AB has a slope of –2/4 = –1/2

    slope of AD and BC would be +2, so draw lines with that slope and length from A and B

    and C is 4,–3 or 4–3i

    D is 0,–1 or 0–i
