1. Perform these transformations on ∆TRL and compute the perimeter of the pre-image and final image.

a. Rotate ∆TRL 180° about the origin and label the resulting image ∆T’ R’ L’.

b. Reflect ∆T’ R’ L’ across the y-axis and label the resulting image ∆T’’ R’’ L’’.

c. Translate ∆T’’ R’’ L’’ according to (x, y) ®(x + 3, y – 3) and label the image ∆T’’’ R’’’ L’’’.
