What is Henagon?
[[File:Monogon.svg|thumb|right|Henagon]] A '''henagon''' (or '''monogon''') is a [[shape]] in [[geometry]]. It is like a [[polygon]], except that it only has one [[side]] and one corner (vertex). Henagons are considered to be impossible to draw, using [[Euclidean geometry]]. This is because the single side would go to [[infinity]]. For example, a line around a [[sphere]] would be considered a henagon. Since it only has one side, there is only one angle. Therefore, all henagons are considered regular shapes. {{Polygons}} [[Category:Polygons|1]] {{Math-stub}}
