This Instructional Activity is a part of the Lesson 6, Unit 2, Grade 8. The purpose of this task is for students to practice showing that two shapes are similar using only a few pre-determined rigid motions and dilations. Some students will start with triangle ABC and take this to triangle DEF while other start with DEF and take this to ABC. While there is "exibility in either direction, one way of getting from DEF to ABC is to "undo" the moves that take ABC to DEF.
