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.

Reflex Angle: Definition & Examples

7. Reflex Angle: Definition & Examples

Reflex angles are used less frequently than other angles, but are easily identified in our everyday environment. This lesson defines reflex angles, explains how to measure them, and examines the relationship between reflex, acute, and obtuse angles.

Remote Interior Angles: Definition & Examples

8. Remote Interior Angles: Definition & Examples

Triangles contain three inside, or interior, angles that when added together, total 180 degrees. In this lesson, you will learn how to calculate remote interior angles.

How to Find the Measure of an Inscribed Angle

9. How to Find the Measure of an Inscribed Angle

Finding the measure of an inscribed angle requires knowing a little information. In this lesson, we'll find the measure of an inscribed angle when we know the measure of the central angle or one or more of the arcs formed by the angle.

Constructing an Angle Bisector in Geometry

10. 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.

How to Measure the Angles of a Polygon & Find the Sum

11. How to Measure the Angles of a Polygon & Find the Sum

Watch this video lesson to learn the one formula that lets you find the measure of angles in any regular polygon. Also, learn how you can tell if you are working with a regular polygon or not.

Using Angles With Vectors

12. Using Angles With Vectors

Vectors are entities that have a magnitude and a direction associated with them. In this lesson, we will investigate how to use this information to determine rectangular coordinates and polar coordinates of vectors.

Defining Negative Angles on the Coordinate Plane

13. Defining Negative Angles on the Coordinate Plane

This lesson will explain how to define negative angles on the coordinate plane and how to draw negative angles on the coordinate plane. Examples and practice problems will be provided.

Measure of an Arc: Process & Practice

14. 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.
