"Mathematics" Great display by you.

cliffordhardin67 comment reminded me of I learned to draw a line with lengh square root of 3 + square root of 5 in 7th grade in Tehran.

Animations are very interesting.

So funny dude ^_^

The only proof I ever remember is using this:

Then the total area if equal to the sum of individual areas, i.e:

(a + b)^2 = 4/2(a * b) + c^2

= a^2 + b^2 + 2ab = 2ab + c^2

= a^2 + b^2 = c^2

nice one

Your never mention..used in a RIGHT-TRIANGLE?!!

0mgg wat about Sohcahtoa?! -__-"

Hey cliffhardin...come on!!..Who doesn't know that!?..I was tooling with Fermat's Theorem when I was six!..Then! I discovered the Wiggles!..haha hey so well..Google Fabio Lanzoni images. I think he's you dad!

this is very-very nice

  True : a squared + b squared = c squared,,,but lets not forget the end .the square root of c squared thereof which is the most common and final mistake of this theorum !!! for instance : lets say a= 2   b=2

                             then: 2 squared =4  + again 2 squared =4 which = 8 squared=64

      the square root of 64 = 8 which is the square root thereof ! Many people forget this last sequence ! the hypotenuse couldnt be 64 ----- it would have to be 8 !!!

Hey Avrilmai, no I don't know that guy. Who is he?

There is a proof of the pythagorean theorem using similar triangles.

who is he?

Hey so well. Have you ever heard of a guy named Fabio?.

About the first picture - it is correct only when a=3, b=4 and the angle between them is 90. In all other values for "a" and "b" this picture is misleading.

just ina pauzzle nisan,in ghazie moheme fisaghorese hamon ke mige dar ye mosalase ghayemol zaviye andaze morabae vatar barabar ast ba majmow morabae 2 zelee digar 

very convincing!!
