A Henagon has 1 side
A henagon has 0 sides.
A henagon has one sides, and a cirle has over 999999999999999999 sides so yeah.
I guess shapes that have few sides have sharper angles for instance a triangle has very sharp corners whereas a henagon has corners but they are very rounded.
10 sides.
There is no formula for how many sides there are in a polygon; the name of the polygon shows how many sides it has.

it is called a henagon is a one sided shape
Ingeometry a henagon (or monogon) is a polygon with one edge and one vertex. It has Schläfli symbol {1}. Since a henagon has only one side and only one interior angle, every henagon is regular by definition. In Euclidean geometry, a henagon is usually considered to be an impossible object, because its single edge would extend to infinity. However, in spherical geometry a finite henagon can be drawn by placing a single vertex anywhere on a great circle. Two henagons can be used to construct a dihedron on a sphere, with Schläfli symbol, {1,2}.

The term for a 21 sided polygon is an icosikaihenagon. Icosi is the Greek for the numerical 20 and henagon means 1.
a henagon is an 11 sided 2-D shape and a 3-D is called an hendecahedron.
a one sided shape is called a henagon and a 2 sided shape is called a digon
You can either call them by n-gon for n sides (i.e. 21-gon) or combine a prefix and suffix (i.e. Icosikaihenagon).
