JOHN: One other issue that I forgot to bring up previously was the fact that after seeing the graph unfolded, a sighted person might think, well you... know, why didn’t you interpret this as an arrow going off the page and leading you to the next graph. Well, when I saw the graph unfolded that made sense, but I thought that this was just another unlabeled angle, because this looks very... similar to this, up in the left-hand corner of the graph, which is clearly an unlabeled angle. 

And if you see any braille there it's simply telling you that that's line P, it's not actually a labeled... angle, there's no number there, as is the case with this one on top here. So, I interpreted it as just another unlabeled angle that was useless to us in this problem.
