Ouch. I never imagined that an "oversized incircle" could isoscelize all seven subtriangles! Had I merely sliced off the largest possible 45-67.5-67.5 and repeated on the remaining 45-22.5-112.5 the process shown here<http://gosper.org/acutefail.png>, I would have found at least -Floor[Tan[69]] solutions instead of Round[Tand[69]]. Many thanks, Hans! --rwg hans>
So, can someone scan in (the picture(s) from) that '61 article? http://chesswanks.com/txt/AcuteIsoscelesDissectionOfAnObtuseTriangle.png
