Anything from none, 2 to 11 sides; and none, 2 to 11 angles. And, the number of equal sides may or may not be the same as the number of equal angles.
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.
Heptagon, octagon, nonagon, decagon, hendecagon, and dodecagon. There are many more.
Oh, dude, a hendecagon has 11 sides, so it's got 11 interior angles. It's like simple math, you know? Each interior angle in a hendecagon measures 147.27 degrees, but who's really counting, right? Math is fun... or something.
2 equal sides and 2 equal angles.
There are 4 equal sides but it has no right angles
The hendecagon is a polygon with eleven sides.
A hendecagon is a regular 11-sided polygon, the angles of which are all 147.27(recurring) degrees. With 11 sides there will be 11 angles, so 147.27 * 11 = 1620 degrees.
They have none
An Equilateral has 3 equal sides and 3 equal angles A scalene triangle has no equal angles and no equal sides.
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.
