Pythagorean Theorem Pythagoras was a Greek philosopher and teacher He lived from 569 to 495 B. C. Often described as the “first pure mathematician”

Pythagorean theorem – only “works” for right triangles For right triangles, where a and b are the legs and c is the hypotenuse of the triangle. There are more than 200 known proofs. Check out a proof of the Theorem online at http://www.keymath.com/x19481.xml Hypotenuse (c) across from the “box” Leg (b) Leg (a)

Ex1: 10 6 x a b Identify your hypotenuse ( c ) The other two sides are legs (it doesn’t matter which on you assign a or b Plug into formula Remember order of operations - SQUARE sides first and solve c 62 + x2 = 102 36 + x2 = 100 -36 x2 = 64 x = 8

Example How high up a wall will a 20’ ladder touch if the ladder is placed 5’ from the wall? Step 1: Identify the hypotenuse and label it “c” Wall Ladder 20’ Step 2: Label the other two sides as “a” and “b” hypotenuse b c Step 3: Plug in and solve. 5’ a or

Ex3: y c a b Follow the steps -5

Classwork Solve for the missing side. Ex. 1 Ex. 2 5 x y = 3 1 Ex. 3 4 2 6 z = 5

Pythagorean Triples Any three positive integers which fit the Pythagorean equation are called Pythagorean Triples. Common Pythagorean Triples are… 3, 4, 5 5, 12, 13 7, 24, 25
