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

There are four types of angles that can be recognized through their number of degrees measured. Learn about these four types of angles, such as right angle, straight angle, acute angle, and obtuse angle.

Complementary Angles: Definition, Theorem & Examples

3. Complementary Angles: Definition, Theorem & Examples

Complementary angles are two angles whose measures added together equals 90 degrees. Learn about the definition and examples of complementary angles and explore theorems involving complementary angles.

Supplementary Angle: Definition & Theorem

4. Supplementary Angle: Definition & Theorem

Supplementary angles are two angles in which the sum of their measures is equal to 180 degrees. Learn about the definition and properties of supplementary angles, and explore the theorems and applications involving supplementary angles.

What Are Adjacent Angles? - Definition & Examples

5. What Are Adjacent Angles? - Definition & Examples

In geometry, adjacent angles are two angles that share a common side and vertex. Learn the definition of adjacent angles and work through examples to gain a greater understanding.

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

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

Understanding angles and angle relationships allows for easier calculation of angle measurement. Learn how to define various types of angles, including vertical, corresponding, alternate interior angles, and how to calculate degree measurement using angle relationships.

Reflex Angle: Definition & Examples

7. Reflex Angle: Definition & Examples

A reflex angle is any angle measured between 180º and 360º added to an acute or obtuse angle to complete a full 360º circle. See example problems and solutions demonstrating the use of reflex angles, as well as how to measure them.

Remote Interior Angles: Definition & Examples

8. Remote Interior Angles: Definition & Examples

Remote interior angles of a triangle do not share a vertex with an exterior angle. Discover how to use the sum of the remote interior angles to find the measure of the exterior angle.

How to Find the Measure of an Inscribed Angle

9. How to Find the Measure of an Inscribed Angle

An inscribed angle occurs when two lines, or chords, share an endpoint. Explore this idea in depth, unpacking how to use central angles and arc lengths to determine the measure of the inscribed angles.

Constructing an Angle Bisector in Geometry

10. Constructing an Angle Bisector in Geometry

In geometry, an angle bisector is a line that splits an angle exactly in half. Learn the method of geometric construction, including the process for constructing an angle bisector.

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

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

A regular polygon is a flat shape with equal sides and equal angles. Learn to identify and measure angles of a polygon including finding the sums of its interior angles, one interior angle, and exterior angles.

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

The measure of an arc can be solved by determining the degree of the angle that intercepts an arc. Learn about the process of measuring an arc, major vs. minor arcs, and real-world practice arc problems.
