Two straight lines cannot enclose a space - therefore three lines is the minimum requirement for a polygon. I would like to note that a digon is a polygon and it has 2 sides. Therefore, the minimum is 2. However, some people call a digon an improper polygon since it contradicts the definition of polygon. A digon can only be made on a sphere, so the answer is never truly correct.

You can either call them by n-gon for n sides (i.e. 21-gon) or combine a prefix and suffix (i.e. Icosikaihenagon).

how many sides does an polygonshave
Yes. A digon can have 2 sides, but only in a spherical geometry. In normal Euclidean geometry both the monogon and the digon have just 1 side.

No.
A 2 sided shape is called a digon

That one where it said dicot, i made a mistake. It is a digon
It is and it isn't. It is a degenerate polygon in Euclidean geometry but it can be a useful concept in some situations.

a one sided shape is called a henagon and a 2 sided shape is called a digon
