Paper on Trisecting an Angle

October 21, 2016

Dom D’Amato, a good, long time friend of mine, wrote a thesis after being challenged by “unsolvable” comments in Wikipedia and other publications about Squaring the Circle using only a straight edge and a compass. He “began a journey toward the exact solutions to four 2500-year-old Greek graphical puzzles:” Trisecting an Angle, Constructing a Nonagon, Squaring the Circle, and Doubling the Cube. Solving trisecting an angle was the key in solving three other drafting puzzles, too!

Note that Dom has used similar principles in developing the algorithms for many RollTrack® measuring software features such as separating roll motion, eccentricity (run-out) and roundness using two probes on a rotating, cylindrical roll.
