monogon

Etymology
.

Noun

 * 1)  A one-dimensional object comprising one vertex and one (not necessarily straight) edge both of whose ends are that vertex.
 * 2) * 2003, Gordon Baker, translator and editor, Ludwig Wittgenstein and Friedrich Waismann, The Voices of Wittgenstein: The Vienna Circle, Routledge, ISBN 0415056446, page 409,
 * We explain to somebody what is a regular quadrilateral constructed within the circle; then a regular triangle and a regular bi-angle. Now we ask him to draw a regular monogon by analogy, and we probably think that he cannot do this. But what if he draws a point on the circle and says that it is a regular monogon?
 * 1)  A two-dimensional object comprising one vertex, one edge both of whose ends are that vertex, and one face filling in the hollow formed by that edge.
 * 2) * 2002, Tao Li, "Laminar Branched Surfaces in 3–manifolds", Geometry & Topology 6, page 158,
 * There is no monogon in $$M-int(N(B))$$, ie, no disk $$D\subset M-int(N(B))$$ with $$\partial D=D\cap N(B)=\alpha\cup\beta$$, where $$\alpha\subset\partial_vN(B)$$ is in an interval fiber of $$\partial_vN(B)$$ and $$\beta\subset\partial_hN(B)$$.

 * An end-compressing monogon for F is a monogon properly embedded in the complimentary [sic] region C which is not homotopic (rel. boundary) into $$\partial C$$.
 * 1)  A single-faceted reflector.
 * 2) * 1999, William L. Wolfe, Infrared Design Examples, Tutorial Texts in Optical Engineering Volume TT36, SPIE Press, ISBN 0-8194-3319-5, page 133,
 * These devices also start with the monogon, a plane mirror, and include the bigon, a two-sided mirror, the trigon, quadrigon, and general n-gons.
