Jan 7	comment	What's a proof that the angles of a triangle add up to 180°? @JoeZeng - To me anything that has calculus in it is atleast a bit more complicated than algebra . :)
Jan 7	comment	What's a proof that the angles of a triangle add up to 180°? @whuber-Could you explain how spherical or hyperbolic geometry is similar to a polygon. Because to me a polygon is a closed two dimensional figure which has only straight line segments as its sides, and the end-points as vertices. Though I am not even aware of hyperbolic geometry except as in a conic section. I have mathematics knowledge only upto what you would expect from an average sophomore, 1st year.
