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?

I don't think you understand the point of trolling. You didn't make anybody mad (well, maybe >>8, but I'm assuming he's just an angry person), you just sound like an idiot. Also, I don't believe that you were trolling.
