This Instructional Activity is a part of the Lesson 6, Unit 3, Grade 8. Students describe the effect of dilations on two-dimensional figures using coordinates. Show the diagram and ask students to look at and write or share a claim about the effect that dilation has on the coordinates of dilated points. In Lesson 5, we found the location of a dilated point by using the knowledge of dilation and scale factor, as well as the lines of the coordinate plane to ensure equal angles, to find the coordinates of the dilated point.
