A hendecagon, also known as an undecagon, is a polygon with eleven sides and eleven angles. Therefore, it has eleven faces if considered in a three-dimensional context, such as in polyhedra. However, when referring to a two-dimensional shape, it is typically said to have one face, which is the flat surface enclosed by its sides.
A hendecagon has 11 lines of symmetry.

A right hendecagon can have no parallel sides because there are eleven sides to a hendecagon. It is not a requirement that there be any pairs of parallel sides in an irregular hendecagon, although there could be one or more pairs.

A 11 sided shape is called a hendecagon.
It depends on what you mean by sides but I suppose you mean not the faces. There are 11 sides which makes it a hendecagon.
