# Ch 22: 4th Grade Math: Symmetry, Similarity & Congruence

This chapter's videos are designed to make learning about symmetry, similarity and congruence fun for 4th grade students. There are lesson quizzes and a chapter exam for you to measure what they have taken away from the chapter.

## 4th Grade Math: Symmetry, Similarity & Congruence - Chapter Summary

Would you like to explain geometry in a way your students won't forget? The funny and age appropriate video lessons in this chapter teach 4th graders about symmetry, similarity, congruence, perpendicular lines, transverse points and more using practical, real-world examples. You can see how well your students have retained the information by using the short, multiple-choice quizzes and a chapter exam.

## Chapter Lessons and Objectives

Lesson Objective
The Line of Symmetry in Geometric Shapes Students learn to recognize the line of symmetry in a triangle, rectangle, square and parallelogram.
Congruence in Geometric Shapes Instructors explain what it means for shapes to be congruent and then test several shapes' congruency.
Similarity in Geometric Shapes In this lesson, students learn what makes shapes similar.
Parallel, Perpendicular and Transverse Lines The lesson explains parallel, perpendicular and transversal lines.
Identifying Parallel Lines in Geometric Shapes Students look for parallel lines in rectangles, squares and parallelograms.
Constructing Perpendicular Lines in Geometry Instructors show how to construct perpendicular lines.
Identifying Perpendicular Lines in Geometric Shapes Students examine triangles, rectangles, squares and trapezoids for perpendicular lines.
Reflection, Rotation & Translation Students explore the definitions of reflection, rotation and translation and ways to identify them.
Reflecting Simple Shapes in a Mirror Line With this lesson, students use a mirror to reflect simple shapes.
Line and Rotational Symmetries of 2D Shapes The lesson leads students to recognize all the line and rotational symmetries of 2D shapes.
