On my last video, I said this about flat-zoids reply to my challenge. My second issue with this is the text itself. It's incorrect. It's an incorrect statement. No triangle has an internal angle of 180 degrees. The three interior angles of a triangle will always have a sum of 180 degrees. A triangle cannot have an individual angle measure of 180 degrees, because then the other two angles would not exist, 180 degree plus 0 degree plus 0 degree. The three angles of a triangle need to combine to 180. Wow I still got no words. You cannot be this dumb five. I mean, he's kind of shooting himself in a foot here, right? He's agreeing with me.
