# Ch 21: 5th Grade Math: Symmetry, Similarity & Congruence

The Symmetry, Similarity and Congruence chapter teaches your 5th grade students how to differentiate between and construct various geometric shapes. Through the chapter's fun video lessons, students are taught how to identify lines of symmetry and draw perpendicular lines. Measure your students' progress by administering the multiple-choice lesson quizzes.

## 5th Grade Math: Symmetry, Similarity and Congruence - Chapter Summary

The Symmetry, Similarity and Congruence chapter's informative video lessons teach your 5th graders about the characteristics of parallel and perpendicular lines. Your students can learn how to use a compass for geometric construction, and they can discover how to determine whether or not shapes are congruent. The included chapter examination can be used to ensure that your students are learning these mathematical concepts.
