# 11 Sided Polygon?

An eleven sided polygon is known as an undecagon or hendecagon. The regular hendecagon is impossible to construct using the conventional Greek rules of geometric construction. Additionally, the sum of interior angles of a hendecagon is 1,620° while the number of diagonals in a regular hendecagon total to 44.
An eleven-sided plane figure is called a hendecagon or an undecagon.
An 11 sided polygon can either be referred to as an Undecagon or a Hendecagon. The regular 11-sided polygon has a Schlfli symbol and cannot be constructed using the classical Greek rules of construction. Its application has been made in the minting of the Canadian dollar coin and the US Susan B Anthony dollar.
A polygon with eleven sides is known as an undecagon or hendecagon. A polygon is a closed figure, which is composed or made up of line fragments that are connected together. Each of the two sides of the polygon meets at a vertex.
An 11 sided polygon can be called either an undecagon or a hendecagon. This is an uncommon shape whose name is not used often, so both names are acceptable to use. You can find more information here: http://www.math.com/tables/geometry/polygons.htm
