Well Euclid had the straight edge and the compass that those are the tools that he had available. He didn't have very good paper. A completely different approach that you can take to construction which is well it's much less classical and so it's less talked about is to use folding paper, instead of a straight edge and a compass Now, if you think about it, folding paper uses nothing. First of all, you can't ever do circles. You'll never be able to fold a circle onto a paper. So, all you have, ever, is straight lines. If you think about, is this stronger or weaker? than this set of tools that Euclid was using, then the intuitive answer is that it must be weaker, but sometimes the intuitive answer is not the right answer. Let me just...
