# Ch 34: 6th-8th Grade Geometry: Introduction to Geometric Figures

The brief and engaging video lessons in this chapter on the introduction to geometric figures give 6th-8th graders a foundation for understanding geometric lines, angles and figures. Lesson transcripts help you and your students identify key terms.

## 6th-8th Grade Geometry: Introduction to Geometric Figures - Chapter Summary

Use the video lessons in this chapter to identify the tools used for constructing the geometric figures and angles that your elementary and middle school students are learning about in class. Easy and entertaining videos describe different tools, including compasses, reflective devices, and straight edges. Moreover, students will learn to use those tools as they practice constructing angles and bisecting segments. You'll also find support if you need it, since our instructors are available for any of your questions. Find out whether your elementary and middle school students are understanding the materials by having them take multiple-choice lesson quizzes.
