Math question

I have a friend, that saids, that sometimes angles in triangle may not sum up to 180 degrees. He also stated once, that there is a shape, that fit into square with finite area, but length of this shape is infinite. Not to mention, that he laughs hen I say, that x/x is always equal to 1. Is he trolling me or is he just a plain idiot?

3) how much is 0/0 faggot?
My 7^th grade math teacher said that it was 1. And she failed me on a quiz for it. Fucking ignorant cunt was a fucking bitch; I hope that she is still rotting away in the fucking jewish operated mind control facility but that she realizes that she is just a fucking slave. Whore.
