Question

3 different proofs for the Pythagorean theorem? It says I have to outline and provide and explanation for each. I know what it is, I just need 3 different ways to prove it! Giving best answer and fan to whomever helps! :)

Answer 1

Well, one way to do it would be taking any triangle (any Pythagorean triple) with the sides proven/found to be what they are using a different method and checking the sides with the Pythagorean theorem.

Answer 2

That helps! I've been pretty stuck on this. Thank you :)

Answer 3

I believe Teddy Roosevelt has a proof he's famous for

Answer 4

what ?

Answer 5

What I said... can using 3 different methods (other than Pythagorean) 3 different times, be like 3 different ways to do it ?

Answer 6

Never mind, it was Garfield?

Answer 7

I mean 3 different ways to prove that pythagorean works.

Answer 8

I was talking to you, Apple 13.

larryboxaplenty, I know someone named Garfield ;)

Answer 9

I think it means there are different proofs for it, so I'm not sure if that counts.lol

Answer 10

Yes, it involved a trapazoid/pentagon/something:

Answer 11

(Yes, President Garfield)

Answer 12

This reminds me of a presintation with diagrams of 15 degree-angles where they explain, based on the proportions of 45-45-90 and 30-60-90 triangles, how to find (lets say) sin 15

(instead of using Sin(45-30) or just looking into trigonometric table that used either (a-b) or the diagram proof).

Answer 13

Anyway... good luck with the project!

Answer 14

Here's my own proof for it:

and yes it was President James Garfield that came up with his own proof.

Answer 15

I don't know if that is specifically my proof. It's just something I came up with on my own. Who knows? Maybe someone like DesCartes or Euclid or Euler came uo with the same thing. LOL
