1. The Pythagorean Theorem
By: Angela Hand

2. Pythagoras Born in Samos, Greece during the sixth century B.C.
Greek philosopher and mathematician
Declared that numbers could uncover the secrets of the universe, limiting and giving shape to matter
Discovered Pythagorean Theorem

3. Use of the Pythagorean Theorem:
The Pythagorean theorem is used to find the length of the missing side in a right triangle.

4. Important facts
Pythagorean theorem can only be used in right triangles
Legs are always the sides adjacent to the 90 degree angle (next to)
It does not matter which leg is a or b
Hypotenuse is always the longest leg called c.

5. What is a right triange?
A right triangle is a triangle with 90 degree angle.

6. Formula
a and b represent the legs
c represents the hypotenuse

7. How formula works... Determine legs and the Hypotenuse hypotenuse leg
Right angle

8. Steps 1. Find legs and hypotenuse 2. Square the legs (a,b)
3. Add legs together
4. Square root the answer
5. Answer is the length of the hypotenuse [c]

9. Square both legs and add
= c2
= c2

10. Square root answer (hypotenuse)
= 25
= 52

11. All together

12. Proof

13. Example problem
Finding a leg

14. Example 2
Find the hypotenuse

15. Applications
Uses:
Designing of ramps. Whether a handicap accessible ramp of a skateboard ramp.
Computing distance between two points, such as in bases in baseball.
