Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates. 12. Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and dilations; given two similar two-dimensional figures, describe a sequence that exhibits the similarity between them.
