#### Storyboard Text

• Ok Class, today I will be teaching you guys about the pythagorean theorem.
• Mr. C thats so easy we leaned that last year. We all know a squared minus b squared = c squared
• A In The Life of GeometryBy: Trey McDonald
• No Catie, its actually a squared + b squared = c squared
• Very good Zach. OK guys now try this problem
•    4
• 3    x
• So 3 squared plus x squared = 4 squared?
• No Catie, it would be 3 squared+ 4 squared = x squared
• Very good Zach, 3d time is the charm Catie. Now try and solve the equation since Zach gave you the formula
• 3 squared = 9. 4 squared =16. So 9+16=25. So the square root of 25 would be 5. x would be 5?
• Now you got it Catie. Wow Mr. C the Pythagorean Theorem really is great.
