  1. PythagoreanTheorem By: Brynn Hughes, Desarae Fletcher, Hannah Willoughby

  2. History A Greek mathmatition and philosopher named Pythagoras founded the Pythagorean theorem.

  3. Different Parts of Right Triangles • Hypotenuse • 2 Legs

  4. The Formula a2 + b2 = c2

  5. What is it used for? The Pythagorean is used for finding the length of the hypotenuse or one of the legs. ? A B

  6. Examples: Finding the hypotenuse a2 + b2= c2 52 +122 =c2 52 = 25 122 = 144 25+144=169 The square root of 169 is 13.

  7. The formula for finding a leg C2 - A2 (or b2 )= B2(or A2)

  8. Finding a leg 92 + b2 = 152 9x9=81 15x15=225 225-81=144 Square 144 B=12

  9. Try it your self A2 = 32 B = 42 C = ?

  10. Answer 3x3=9 4x4=12 12+9=21 The square root of 21 is 4.6, rounded to the nearest tenth.
