About This Chapter

The Triangle Trigonometry unit of this High School Trigonometry Homeschool Curriculum course is designed to help homeschooled students learn about triangle trigonometry. Parents can use the short videos to introduce topics, break up lessons and keep students engaged.

Who's it for?

This unit of our High School Trigonometry Homeschool Curriculum course will benefit any student who is trying to learn about triangle trigonometry. There is no faster or easier way to learn about triangle trigonometry. Among those who would benefit are:

  • Students who require an efficient, self-paced course of study to learn about the Pythagorean Theorem, right triangles and trigonometric ratios.
  • Homeschool parents looking to spend less time preparing lessons and more time teaching.
  • Homeschool parents who need a math curriculum that appeals to multiple learning types (visual or auditory).
  • Gifted students and students with learning differences.

How it works:

  • Students watch a short, fun video lesson that covers a specific unit topic.
  • Students and parents can refer to the video transcripts to reinforce learning.
  • Short quizzes and a Triangle Trigonometry unit exam confirm understanding or identify any topics that require review.

Triangle Trigonometry Unit Objectives:

  • Understand the relationship between similar right triangles and trigonometric ratios.
  • Explain and apply the Pythagorean Theorem to problems with right triangles.
  • Use the Pythagorean Theorem to solve distance problems without a right triangle.
  • Use the Pythagorean Theorem and trigonometric functions together to solve problems.

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.
