That's a solid isn't it? 3-D
For some reason I guessed the OP was asking about a plane figure. 2-D

Sounds like the brand name of a tranquilizer! Thanks.

For my purposes it could be either I'm looking for a word that I associated with the number 20. Context: A 20th anniversary, so 2D or 3D makes no difference in this instance.

So did I.

20 sides - icosagon
20 faces - icosahedronicosahedral is an adjective.

So is icosagonal.
The (n-1)-D edge of an n-D polygon is called "face" and the 1-D edge of an n-D polygon is called "edge". Here, n is any positive integer.

Any positive integer?...I suppose (n=1) you could call the endpoints of a line segment "edges" and its length a "face", but you'd have to explain such aberrant behavior to anyone listening..r
