Help! I have to graph my answer to this problem: ADFG has vertices D (–2, 4), F (–3,1), and G (–1, 2). Find the vertices of the image after the rotation of 180° about the origin.

  • AlgebraB -

    after a 180° rotation
    (x,y) ----> (-x,-y)

    so
    D(-2,4) -----> D'(2,-4)
    same for the other points,

    it is really that easy.
