As you may know term "polygon" might mean few different things 
and its meaning has to guessed from context.
By some reason I have to use few of these meaning in one place.


So I converge to the following convention:


Polygon is a cyclically ordered set of points.
Then I could define its *sides*;
I can say then if the polygon is *simple*;
for simple polygons I can define its *interior*.
And then I need a term for the *set formed by the union 
of the interior and all the sides of the polygon*.
(Maybe "body of the polygon" or "solid polygon"?)


Did you see a term for this used somewhere (I need a term different from "polygon")?
