 Compositions of Transformations Terms of Use    Contact Person: Donna Roberts  Directions: Grab paper (graph paper) and pencil. Rotations are centered at the origin unless otherwise stated.

1.
Starting with point A (-4, -5), which single translation will produce the same image as the following sequence of translations:
(x, y) → (x - 1, y + 5), followed by
(x, y) → (x + 4, y + 2), followed by
(x, y) → (x - 5, y - 7) ?
Choose:
 (x, y) → (x - 6, y - 5) (x, y) → (x - 2, y) (x, y) → (x - 1, y + 2) (x, y) → (x - 5, y) 2.

Choose:   All of these compositions. 5 Given the graph at the right with B(-6,1), U(-3,7), G(-2,1) and B'(0,-6), U'(6,-3), G'(0,-2). Describe a sequence of transformations that was used to carry ΔBUG onto ΔB'U'G'. 6.
