Georg Mohr demonstrated that only one of the pieces of equipment for this process is necessary. It can be done with a regular heptadecagon, pentagon, and triangle, but not with a nonagon or heptagon. In general, it can be done with any regular polygon whose number of sides' odd factors are distinct Fermat primes. The three most famous problems involving this are impossible: the quadrature of a circle because it involves creating a transcendental ratio and doubling a cube and trisecting an angle because they involve solving cubic equations. FTP, name this process, used to solve geometric problems only by drawing straight lines and arcs of circles.
