This Instructional Activity is a part of the Lesson 8, Unit 3, Grade 8. In the given picture, we have triangle DEF that has been dilated from center, by scale factor r=3. It is noted by D'E'F'. We also have triangle, which is congruent to triangle D'E'F'. We want to describe a sequence that would map this triangle onto triangle DEF. This is similar to what we did in the last example.
