My Pythagorean Theorem proof Remember that (z-s)+s=z, that might help.

Ok, I just realized that you can't see the math...

Well, the box in the middle is a square, with side b. The large triangles have side c and are isosceles. The trapezoids have bases 2a/sqrt3 and a/sqrt3 with height a/sqrt3. With 2 congruent trapezoids. Thus...

2(Atrap)=(Atr+Atr')-Asq
2(1/2)(a/sqrt3)(2a/sqrt3+a/sqrt3)=(c^2/2+c^2/2)-(b^2)
a/sqrt3(3a/sqrt3)=c^2-b^2
3a^2/3=c^2-b^2
a^2=c^2-b^2
a^2+b^2=c^2 #### Cosmo

Re: My Pythagorean Theorem proof

You're one smart kid, Iggy I'm a bit confused as to what this has to do with the theory of time travel. You might want to clue us in...

Nothing. But hey! it's another formula brought to you by Iggy & Pythagoras. What more did you want?

Re: My Pythagorean Theorem proof Thanks...There really is no forum for non-time travel yet sciency things, so I just put it here...Mostly because I sometimes have time travel theories and sometimes I don't...I just want to be able to find it all on one forum. #### sosuemetoo

Second that Susan. Good to see you posting iooqxpooi. I don't understand what your original post said at all. Not enough brain pan on my end.
