The hendecagon is a polygon with eleven sides.
A hendecagon can have upto 5 pairs of parallel lines.

The sum of the interior angles of a hendecagon is 1620 degrees.
Hendecagon
regular hendecagon has internal angles of 147.27 degrees. The area of a regular hendecagon with side length a is given byA regular hendecagon is not constructible with compass and straightedge; this animation shows an approximation:
The hendecagon is a polygon with eleven sides.
A hendecagon has 11 lines of symmetry.
Presumably the question concerns a hendecagon. The sum of the interior angles of a n-gon are (n-2)*180 degrees. For a hendecagon, the sum of the interior angles would be 9*180 = 1620 degrees. If the hendecagon is regular, then all its interior angles are equal, and each is then 1620/11 = 147.2727.. degrees.
A hendecagon can have upto 5 pairs of parallel lines.
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.
