Re: Geometry problem
[ QUOTE ]
Ok, now I subtract points from myself for agreeing to a fake solution. When you choose to traverse along an integer path, you are not necessarily guaranteed to land at a "corner." It is necessary to be at a corner before you are guaranteed to have an integer path along which to travel.
Try again.
[/ QUOTE ] wait a minute, yes you are guaranteed to land at the corner point with at least one other R_i, but i am not sure i can prove that the path necessarily hits the other side.
can you visualize a corner of an R_i that doesn't share that corner with another R_i? maybe you could demonstrate with a pic because i can't see it right now.
