This Instructional Activity is a part of the Lesson 3, Unit 2, Grade 8. This activity investigates dilations with no grid. Students have seen these for the first time in the warmup, which had a ray drawn between two points. That scaffold has been removed here so the teacher may need to provide guidance by suggesting that students draw appropriate rays. Encourage students to measure distances carefully at first, since the problem statement does not state that the image of each point, after the dilation indicated, is one of the labeled points.
