    As far as I can see, the only way to get something like a square would be to plot a point at (5,0)

    Hello, dgenerationx2!

    You couldn't type the question for us?


    Quadrilateral ABCD has vertices with coordinates:
    . . A(1,-4),\;\;B(-3,0),\;\;C(1,4)

    Determine the coordinates of D for which ABCD is a square.
    Did you make a sketch?
    Code:
                  | (1,4) 
                  |   o C
                  | *   *
                  *       *
                * |         *
            B *   |           *  D
        - - o - - | - - - - - - o - -
        (-3,0)*   |           *
                * |         *
                  *       *
                  | *   *
                  |   o A
                  | (1,-4)

    You can "eyeball" where D is . . . can't you?
