1. Perform these transformations on ∆TRL and compute the perimeter of the pre-image and final image. Show your computation for finding the image vertices and for finding the perimeters.

a. Rotate ∆TRL 180¢X about the origin and label the resulting image ∆T¡¦ R¡¦ L¡¦.

b. Reflect ∆T¡¦ R¡¦ L¡¦ (the image from a) across the y-axis and label the resulting image ∆T¡¦¡¦ R¡¦¡¦ L¡¦¡¦.

c. Translate ∆T¡¦¡¦ R¡¦¡¦ L¡¦¡¦ (the image from b) according to (x, y) „_(x + 3, y ¡V 3) and label the image ∆T¡¦¡¦¡¦ R¡¦¡¦¡¦ L¡¦¡¦¡¦.
