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 180óX about the origin and label the resulting image ∆TíŽ RíŽ LíŽ.
b. Reflect ∆TíŽ RíŽ LíŽ (the image from a) across the y-axis and label the resulting image ∆TíŽíŽ RíŽíŽ LíŽíŽ.
c. Translate ∆TíŽíŽ RíŽíŽ LíŽíŽ (the image from b) according to (x, y) ä_(x + 3, y íV 3) and label the image ∆TíŽíŽíŽ RíŽíŽíŽ LíŽíŽíŽ.
