Write a sequence of transformations that maps triangle ABC onto triangle A''B''C''.
--------------------------------------…
A in ABC is 1,9, B in ABC is 3,12, and C in ABC is 4,4.

A'' in A''B''C'' is 3,-3, B'' in A''B''C'' is 5,-6, and C'' in A''B''C'' is 6,2.

  1. so, we have

    (1,9) -> (3,-3)
    (3,12) -> (5,-6)
    (4,4) -> (6,2)

    x -> x+2
    y -> 6-y = 3-(y-3)

    So,
    shift right 2
    reflect across the line y=3.
