This Instructional Activity is a part of the Lesson 4, Unit 1, Grade 7. The purpose of this activity is for students to determine that figures are not scaled copies, even though they have either corresponding angles with equal measures or corresponding distances multiplied by the same scale factor. This shows that to determine one figure is a scaled copy of another, we have to check both the corresponding angles and the corresponding distances.
