Faces

What is it faces?

polygons

If your talking about in the viewport stats where it shows polygons and faces, that is because one is for tris and one for everything else.

Yep I talked about viewport stat. Thanks.

Polys = number of tris, quads and n-gons in the scene

Faces = number of faces(triangles) that make up the display of the tris, quads and n-gons in the scene.

If using quads/n-gons to build a model, it is important that you understand the underlying faces(triangulation) and how their windings can affect display/rendering.

Please note:
There is a difference between "Wireframe" and "Wire Mesh" view.
"Wireframe" will show edges that are on polys
"Wire Mesh" will show edges on Polys and faces

Wiremesh display is found:-
View > Object Shading > Object individual Shading > Wire Mesh/Wire Mesh all

Thank you very much)
