The Pythagorean Theorem

Week 6: The Pythagorean Theorem

Start Here

If you are trying to get to the other corner of a park, is it faster to walk around the sides or to go across from corner to corner? How do you know?

Goals

You can use this as a checklist to monitor and measure your learning! At this end of this module, you should be able to:

- Explain how the Pythagorean Theorem can be used
- Use a formula to find the length of a missing side of a right triangle

Check out the LESSON ACTIVITIES next.

Activities

You can also use this as a checklist to make sure you've finished the entire assignment:

- Watch a video introduction to the theorem Part 1

Draw a right triangle and apply the Pythagorean theorem in Part 2
- Practice using the formula in Khan activities in Part 3
- Optional - Join a group video chat on Tuesday, October 20th, 6-7pm

Estimated time to complete: 2-3 hours

These activities are due by 9pm on Tuesday, October 20th

Part 1 - Watch a video introduction

The Pythagorean Theorem can be used to find the length of a missing side of a right-triangle. In other words, if we know the lengths of 2 sides of a right-triangle (like in this sample picture), we can use a formula to find the length of the third side. In other words, we can figure out if it's faster to cut through a park or walk around the sides.

Check out this short video introduction on how to use the Pythagorean Theorem.

Then move on to PART 2 below!

Part 2 - Draw a real-world example

Now that we better understand what the Pythagorean Theorem is and how ti can be used, let's apply to the real-world. When is a good situation when you could use the formula to find useful information? Click the Google Doc icon to get started!
