Why are Circles Similar?

Students learn how to prove that all circles are similar using the three transformations (reflection, dilation, translation) on a unique circle. The lesson takes students through multiple-step transformations to show a proof of circle similarity. A Socratic discussion is used as closure to aid in the comprehension of circle similarity.
