Ch 30: 8th Grade Math: Introduction to Geometric Figures

About This Chapter

This chapter utilizes short, interesting videos to teach eighth graders how to make geometric constructions and define points, lines and angles. If your student needs further clarification, they can submit questions to an instructor.

8th Grade Math: Introduction to Geometric Figures - Chapter Summary

Your eighth grader can use the straightforward and brief videos found in this chapter to bolster their knowledge of angles and line segments. Students will receive instruction on angle types and line bisection, as well as be able to practice constructing geometric figures. The available quizzes and worksheets can be accessed at any point during the lesson, to test student knowledge or practice concepts.

Chapter Lessons and Objectives

Line Segments & Rays: Definition & Measurement

1. Line Segments & Rays: Definition & Measurement

Watch this video lesson to learn the difference between a line segment and a ray. You will also learn how to measure and add line segments. Learn why you can't measure or add a ray.

Points, Lines & Angles in Geometry

2. Points, Lines & Angles in Geometry

After watching this video lesson, you should understand the basic terms that form the foundation of geometry. Learn what a point is, what a line is, what an angle is, and learn about a special type of angle called a right angle.

Geometric Constructions Using Lines and Angles

3. Geometric Constructions Using Lines and Angles

Watch this video lesson to learn about geometric construction and how you can copy line segments and angles without using any numbers. All you need is a straight edge and a compass.

Line Segment Bisection & Midpoint Theorem: Geometric Construction

4. Line Segment Bisection & Midpoint Theorem: Geometric Construction

Watch this video lesson and you will learn how to bisect a line segment without measurements using just a compass and a straight edge. You'll also learn about the midpoint theorem, which lets you calculate the midpoint if you have the measurements.

Dividing Line Segments into Equal Parts: Geometric Construction

5. Dividing Line Segments into Equal Parts: Geometric Construction

Watch this video lesson to learn one way to easily divide any line segment into as many equal parts as you need. Also, learn where in real life this skill comes in handy.

Types of Angles: Vertical, Corresponding, Alternate Interior & Others

6. Types of Angles: Vertical, Corresponding, Alternate Interior & Others

In addition to basic right, acute, or obtuse angles, there are many other types of angles or angle relationships. In this lesson, we will learn to identify these angle relationships and discuss their measurements.

Constructing an Angle Bisector in Geometry

7. Constructing an Angle Bisector in Geometry

Watch this video lesson to learn a cool way to split an angle in half. You can use this method to split a pie slice in half where you can be sure each side is equal.
