Re: теорема ферма

(Link)
english version

Any triple of positive integer numbers could represent a triangle on a euclidian plane. That means the theorem of cosines is in action.
And Fermat's theorem comes down to a question of when a cosine is a rational number.
But by the definition of a cosine it will only be rational for Pythagorian triples.
