This Instructional Activity is a part of the Lesson 8, Unit 3, Grade 8. In the given picture, we have triangle that has been dilated from center by a scale factor of r = 1/2. It is noted by A'B'C'. We also have triangle, which is congruent to triangle A'B'C'. Remind students of the work they did in Lesson 3 to bring dilated figures back to their original size. Describe the sequence that would map triangle onto triangle.
