## Who's it for?

This chapter of our SAT Prep Tutoring Solution will benefit any student who is trying to learn triangles and trigonometric rates and earn better grades. This resource can help students including those who:

- Struggle with understanding triangle properties, the applications of sine and cosine, and the steps for determining trigonometric ratios or any other triangles and trigonometric rates topic
- Have limited time for studying
- Want a cost effective way to supplement their math learning
- Prefer learning math visually
- Find themselves failing or close to failing their complex numbers unit
- Cope with ADD or ADHD
- Want to get ahead in SAT prep
- Don't have access to their math teacher outside of class

## Why it works:

**Engaging Tutors:**We make learning about triangles and trigonometric rates simple and fun.**Cost Efficient:**For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.**Consistent High Quality:**Unlike a live SAT tutor, these video lessons are thoroughly reviewed.**Convenient:**Imagine a tutor as portable as your laptop, tablet or smartphone. Learn triangles and trigonometric rates on the go!**Learn at Your Pace:**You can pause and re-watch lessons as often as you'd like, until you master the material.

## Learning objectives

- Review the properties of triangles
- Go over how to spot similar triangles
- Identify the applications for similar triangles
- Examine cosine and sine
- Describe trigonometric similarity and ratios
- Analyze the Pythagorean Theorem and its applications
- Utilize the Pythagorean Theorem to measure distances
- Make use of sample problems to find trigonometric ratios

### 1. Properties of Shapes: Triangles

Isosceles, equilateral and obtuse, oh my! These are terms for triangles. But, what do they mean? In this lesson, we'll explore the properties of triangles and take a closer look at the different types of triangles you may encounter.

### 2. How to Identify Similar Triangles

Similar triangles have the same characteristics as similar figures but can be identified much more easily. Learn the shortcuts for identifying similar triangles here and test your ability with a quiz.

### 3. Applications of Similar Triangles

Similar triangles are used to solve problems in everyday situations. Learn how to solve with similar triangles here, and then test your understanding with a quiz.

### 4. Special Right Triangles: Types and Properties

Not all right triangles are the same. In this lesson, we'll look at two special right triangles (30-60-90 and 45-45-90) that have unique properties to help you quickly and easily solve certain triangle problems.

### 5. Trigonometry: Sine and Cosine

Learn an easy trick to help you solve trigonometry problems, including problems with sine, cosine and inverse trig functions. At the end of this lesson, you'll know what SohCahToa means and how to use it.

### 6. 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.

### 7. 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.

### 8. 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.

### 9. 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.
