How to Estimate Angle Measures

1. How to Estimate Angle Measures

In real life it takes special equipment to accurately measure angles, but you can make a pretty good guess if you know a few tricks. We'll discuss some of those in this lesson.

Complementary, Supplementary, Vertical & Adjacent Angles

2. Complementary, Supplementary, Vertical & Adjacent Angles

After watching this video lesson, you will know how to locate complementary, supplementary, vertical, and adjacent angles. You will understand how easy it is to visually see them. You will also know what to look for.

How to Find Interior Angles

3. How to Find Interior Angles

After completing this lesson, you will be able to describe what an interior angle is and find its measurements. We will explore interior angles in regular polygons such as equilateral triangles, squares, and pentagons.

Types of Angles: Right, Straight, Acute & Obtuse

4. 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.

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

5. 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 the Angles of a Polygon & Find the Sum

6. 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.

Triangle Congruence Postulates: SAS, ASA & SSS

7. Triangle Congruence Postulates: SAS, ASA & SSS

When we have two triangles, how can we tell if they're congruent? They may look the same, but you can be certain by using one of several triangle congruence postulates, such as SSS, SAS or ASA.

The AAS (Angle-Angle-Side) Theorem: Proof and Examples

8. The AAS (Angle-Angle-Side) Theorem: Proof and Examples

When trying to find out if triangles are congruent, it's helpful to have as many tools as possible. In this lesson, we'll add to our congruence toolbox by learning about the AAS theorem, or angle-angle-side.

What is a Scale Factor? - Definition, Formula & Examples

9. What is a Scale Factor? - Definition, Formula & Examples

How does a carpenter know the correct length of a room on a blueprint? How can a graphic designer tell if an enlarged picture will be distorted? Learn what a scale factor is and how you can use it in this article!

Solving Real World Problems With Compass Bearings

10. Solving Real World Problems With Compass Bearings

There are several methods to indicate which way an object is heading by using a compass. In this lesson, we will focus on three figure compass bearings to solve real world problems.

Transformations in Math: Definition & Graph

11. Transformations in Math: Definition & Graph

In geometry, transformation refers to the movement of objects in the coordinate plane. This lesson will define and give examples of each of the four common transformations and end with a quiz to make sure you are moving in the right direction.
