Trigonometric Ratios and Similarity

1. Trigonometric Ratios and Similarity

Where do terms like sine, cosine and tangent come from? In this lesson, we'll learn about how similarity with right triangles leads to trigonometric ratios.

Practice Finding the Trigonometric Ratios

2. Practice Finding the Trigonometric Ratios

So you know what sine, cosine and tangent are. Great! But how do you use them? Find out how in this lesson as we find missing sides and angles using trigonometric ratios.

The Pythagorean Theorem: Practice and Application

3. The Pythagorean Theorem: Practice and Application

The Pythagorean theorem is one of the most famous geometric theorems. Written by the Greek mathematician Pythagoras, this theorem makes it possible to find a missing side length of a right triangle. Learn more about the famous theorem here and test your understanding with a quiz.

Finding Distance with the Pythagorean Theorem

4. Finding Distance with the Pythagorean Theorem

How much faster is it to cut the corners in a race around the block? In this lesson, review the Pythagorean Theorem, and figure out how to solve without a right triangle.

Trigonometry and the Pythagorean Theorem

5. Trigonometry and the Pythagorean Theorem

Explore how the Pythagorean Theorem can be used in conjunction with trigonometric functions. In this lesson, take an inverse trigonometric function, and define all three sides of a right triangle.

Perfect Square: Definition, Formula & Examples

6. Perfect Square: Definition, Formula & Examples

In this lesson, you'll learn what perfect squares are and view a few examples of them. You'll also discover the formula for creating perfect squares. Then, you can test your new knowledge with a brief quiz.

Solid Figures: Definition, Properties & Examples

7. Solid Figures: Definition, Properties & Examples

Solid figures are everywhere around us. In this lesson, we'll learn what solid figures are, and we'll explore some common types of solid figures. After going through the lesson, you will be able to test your new-found knowledge with a quiz.

Sphere: Definition & Formulas

8. Sphere: Definition & Formulas

A sphere is a perfectly round three-dimensional object. This lesson will give a mathematical definition of a sphere, discuss the formulas associated with spheres and finish with a quiz.

Trigonal Bipyramidal in Molecular Geometry: Bond Angles & Shape

9. Trigonal Bipyramidal in Molecular Geometry: Bond Angles & Shape

In this lesson, you will learn about trigonal bipyramidal molecules. We will discuss the angles formed within the molecules and look at a few examples. You can then take a brief quiz to see what you learned.

What is a Triangle Pyramid? - Definition & Formula

10. What is a Triangle Pyramid? - Definition & Formula

In this lesson, you will learn the definition of a triangular pyramid. You will also learn the formulas to find the base area, surface area, and volume of a triangular pyramid. Then work through an example calculation of each.

What is Trigonometry? - Functions, Formulas & Applications

11. What is Trigonometry? - Functions, Formulas & Applications

There is more to trigonometry than just sines and cosines. It can help when you need to build certain things or when you need to calculate certain distances. Learn about the usefulness of trigonometry and how triangles and circles are tied together.
