Lesson 7.1.1 Lesson Objective: Students will review their skills of determining missing side lengths of similar polygons, identifying congruent polygons, using the Pythagorean Theorem, and using the Triangle Angle Sum Theorem. Students will learn the definition of congruence in terms of rigid transformations. They will then determine if two triangles are congruent by comparing all three corresponding angle measurements and all three corresponding side lengths.

Problem 7-3 Facilitators lead your teams through Problem 7- 3 on page 366 of your book. Read the problem out loud or have someone read it while everyone in the team follows silently.
