About This Chapter

The Angles chapter of this Saxon Algebra 1/2 Companion Course helps students learn the essential lessons associated with angles. Each of these simple and fun video lessons is about five minutes long and is sequenced to align with the Angles textbook chapter.

How It Works:

  • Identify the lessons in the Saxon Angles chapter with which you need help.
  • Find the corresponding video lessons with this companion course chapter.
  • Watch fun videos that cover the angles topics you need to learn or review.
  • Complete the quizzes to test your understanding.
  • If you need additional help, rewatch the videos until you've mastered the material or submit a question for one of our instructors.

Students will learn:

  • How to identify an angle's vertex
  • What right, straight, obtuse and acute angles are
  • Theorems that apply to complementary angles
  • How supplementary angles are defined
  • What adjacent angles are
  • Definitions for corresponding and vertical angles
  • How angles are measured with a protractor
  • How an angle bisector is constructed in geometry
  • The process for determining the measure of an arc

How to Identify the Vertex of an Angle

1. How to Identify the Vertex of an Angle

Are you confused as to what a vertex is? Don't fret. This lesson explains in really simple terms with several different examples how you can easily spot the vertex of an angle.

Types of Angles: Right, Straight, Acute & Obtuse

2. Types of Angles: Right, Straight, Acute & Obtuse

Angles are everywhere. Learn about the different types of angles we use in mathematics, including right angles, acute angles, obtuse angles, and straight angles. See if you can tell the difference with a quiz.

Complementary Angles: Definition, Theorem & Examples

3. Complementary Angles: Definition, Theorem & Examples

In this lesson, we will define complementary angles and see how they may appear in diagrams. We will discuss two common theorems that involve complementary angles. Then you can test your knowledge with a quiz.

Supplementary Angle: Definition & Theorem

4. Supplementary Angle: Definition & Theorem

There are many important angle pairs in geometry. In this lesson, we'll learn about supplementary angles, including what they are, where they are used, and why you need to know about them.

What Are Adjacent Angles? - Definition & Examples

5. What Are Adjacent Angles? - Definition & Examples

In this lesson, you will learn how to identify whether angles are adjacent. After looking at several examples, you will be able to test your knowledge with a quiz.

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.

How to Measure Angles with a Protractor

7. How to Measure Angles with a Protractor

You're surrounded by angles at home, at school, and even when you're walking down the street. In this lesson, you'll learn how to measure different angles using a protractor.

Constructing an Angle Bisector in Geometry

8. 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.

Measure of an Arc: Process & Practice

9. Measure of an Arc: Process & Practice

What is the measure of an arc? And what is the difference between a minor arc and a major arc? Find out all that and practice finding the measure of an arc in this lesson.
