Trisecting an angle correctly up to arcminute

Journal Article


Abstract


  • We present a simple compass-and-straightedge construction method of approximately trisecting an angle. This method is applicable to both acute and obtuse angles. With an original angle α, the construction gives an angle τ with error |ε| = |τ − α/3| < .0155◦.
