11.2 Proving Figures Similar using Transformations Date: A similarity transformation is a transformation in which an image has the same shape as its pre-image. Are congruent figures similar figures? Are all circles similar? Ex. 1 Determine whether the figures are similar using similarity transformations.

Ex. 2 For each pair of similar figures, find a sequence of similarity transformations that maps one figure to the other.
