It is impossible to trisect angles with straightedge and compass alone, but many people try and think they have succeeded. This book is about angle trisections and the people who attempt them. Its purposes are to collect many trisections in one place, inform about trisectors, to amuse the reader, and, perhaps most importantly, to reduce the number of trisectors. This book includes detailed information about the personalities of trisectors and their constructions. It can be read by anyone who has taken a high school geometry course.

Fur viele Menschen besitzen die Zahlen eine Bedeutung, die uber den Zahlenwert hinausgeht, sie haben eine innere Natur und einen magischen Charakter.
