Types of Angles: Right, Straight, Acute & Obtuse

1. 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.

Triangle Sum Theorem: Definition & Examples

2. Triangle Sum Theorem: Definition & Examples

In this lesson, we will learn about the Triangle Sum Theorem. We will also look at how useful the Triangle Sum Theorem is when looking for missing angle measurements inside of a triangle.

Similar Triangles: Definition, Formula & Properties

3. Similar Triangles: Definition, Formula & Properties

Similar triangles are triangles with equal corresponding angles and proportionate sides. This lesson will explore the proprieties of similar triangles and explain how to apply these properties to solve for the length of missing sides.

Perimeter of Triangles and Rectangles

4. Perimeter of Triangles and Rectangles

Without realizing it, we calculate and use the perimeter of triangles and rectangles in regular everyday situations. Learn more about the perimeter of triangles and rectangles in this lesson, and test your knowledge with a quiz.

Area of Triangles and Rectangles

5. Area of Triangles and Rectangles

How do you find out the area of rectangles and triangles? Learn how in this lesson! We'll look at the formulas, then practice solving problems for each shape.

Circles: Area and Circumference

6. Circles: Area and Circumference

Understanding how to calculate the area and circumference of circles plays a vital role in some of our everyday functions. They serve as the foundation for operating with three-dimensional figures. Learn more about the area and circumference of circles in this lesson.

How to Find the Diameter of a Circle: Definition, Formula & Example

7. How to Find the Diameter of a Circle: Definition, Formula & Example

Learn the definition of the diameter of a circle and how to find it using a simple formula. See some examples, then test your knowledge with a short quiz.

How to Find the Radius of a Circle: Definition & Formula

8. How to Find the Radius of a Circle: Definition & Formula

In this lesson, you will discover the definition of a radius. You will also learn how to find the radius of a circle using three different formulas based on diameter, circumference, and area.

Radians & Degrees on the Unit Circle

9. Radians & Degrees on the Unit Circle

Angles are important in all kinds of fields, such as construction, science, math, navigation, and engineering. There are two units that we can use to measure angles: degrees and radians. In this lesson, learn how to use these units and how they are related to the unit circle.
