## Symmetry, Similarity and Congruence - Chapter Summary and Learning Objectives

Symmetry, similarity and congruence all speak to ways geometric shapes are alike, yet the terms are mathematical with specific definitions and characteristics. The lessons in this chapter present instructional material on each by slicing up the subject matter into short videos. You can then take a short self-assessment quiz to verify your understanding of the material. In addition, you can ask the instructor questions if you want. When you are finished with the lessons in this chapter, you should know:

• The concept of symmetry in math
• Similarity in geometric shapes
• Congruence in geometric shapes
