Talk:Frustum

From Wikipedia, the free encyclopedia

Should a frustum be classified as a polyhedron?

If a truncated cone is a frustum, then not all frusta are polyhedra.

Am I correct? Please discuss.

I don't know any specific policy on category usage. I'd think it can make sense to include a category even if it doesn't apply to all forms or definitions. Tom Ruen 21:04, 10 January 2007 (UTC)
