Neusis Construction

A geometric construction, also called a Verging Construction, which allows the classical Geometric Constructionrules to be bent in order to permit sliding of a marked Ruler. Using a Neusis construction, Cube Duplicationand angle Trisection are soluble. Conway and Guy (1996) give Neusis constructions for the 7-, 9-, and 13-gons whichare based on angle Trisection.
