    Question Indirect proof

    ODEF is a square. In terms of a, find

    a. The coordinates of points E and F
    b. The area of the square
    c. The midpoint of FD
    d. The midpoint of OE

    Point O= (0,0)
    Point D= (2a,0)


    I do not understand how to solve this problem and what it has to do with indirect proofs.

    HELP!!!

    A square has congruent sides. Therefore E=(2a,2a) & F=(0,2a).
