This Instructional Activity is a part of the Lesson 13, Unit 1, Grade 8. In this activity, students examine two figures made out of disjoint pieces: the outline of a face, two eyes, and a mouth. The disjoint pieces are congruent to one another taken in isolation. But they are not congruent taken as a collective whole because the relative positions of the eyes, mouth, and face outline are different in the two images. This activity reinforces a goal of the previous activity.
