2-sided polygon

well, from now on there is no luv triangle. it's a luv circle. no, oval, wait, those don't have any edges. are there any 2-sided polygons? nope. fine, alright from now on it's a love line (u know, a straight line) becuase thre's only a A nd B, there ain't no more C. There may be a D though, so they can have their little love triangle, but for now, it's a love line. and C isn't a part of it....
