is triangle DEF with verticies D(-3,-4), E(2.-5), F(0,1) a right triangle?

    Ah, a slightly different twist :)

    For the third time, find the squares of the lengths of the three sides.

    If the sum of the squares of the two smaller sides = the square of the third side, it is.
    like if
    c^2 = a^2 + b^2 it is right
