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.
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.
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.
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.
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.
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.
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.
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.
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.
