Understanding the Pythagorean Theorem for Triangles

1. Pythagorean theorem

2. What is Pythagorean theorem • It is the way you find the area of an triangle. • It has three sides. • A. one of the three sides also called a leg • B. one of the three sides also a leg • C. is the hypotenuse the third side of the triangle • If u multiple the two legs they make the hypotenuse.

3. Lets look at a right triangle • An right triangle has three side that form at a 90 degree angle.

4. Triangle • Pythagorean theorem works on all triangles, but it most commonly used on right triangles. 90 degree

5. When will Pythagorean theorem be used • Pythagorean theorem would be used to find the area of an triangle. Ex. 9 8 x

6. Why is Pythagorean theorem • It is important to architects to know a roof that shaped like an triangle, or the shape of an sculpture for an artist .

7. Question • Ok lets work out a problem using Pythagorean theorem. ? 5 6

8. …Continuing question • To find the hypotenuses you have to multiple the two legs A=5 B=6. 5*6=30 A*B=C

9. Finishing question • After you find all the numbers you then square root them and add them. Ex. 2 5

10. Example of Pythagorean theorem • I'm going to use an right triangle as an example. C A B

11. Pythagorean theorem • Five things we learned today about Pythagorean theorem. • 1.pythagorean theorem is the how you find the area of an triangle. • 2.pythagorean theorem has three legs • 3. Pythagorean theorem biggest leg is the hypotenuse. • 4. the right triangle is the most common triangle used for Pythagorean theorem. • 5. the most important thing to know is that a + b always =c
