Geometry Unbound

Illustration of Desargues' theorem
Yesterday I posted on The Jewish Coffin Problems of Moscow State University. Part of that post included links to two sets of simple to describe but extremely difficult to solve math problems -- so called "coffin problems" -- that were given to Jewish applicants and students and other "undesirables" to try to keep them out of the prestigious program. There were hints and solutions included in the problem sets, but, you know, those only go so far and don't provide a general methodology. So, today here's an open source book that was originally written for Mathematics Olympiad students: Geometry Unbound. This version, by the way, has no diagrams (you get what you pay for), but it's still very accessible.
