Usage: corner/vertex - side/face?

What is more common (in everyday English, not in mathematical jargon): corner or vertex, side or face? Peter Schmitt 23:30, 5 June 2009 (UTC)

Vertex is hardly *ever* used in regular English. Side and face, of course, also mean many different things, but they are both very common words. In regular English, however, you'd almost certainly say, "A rectangle has six sides." "A door has six sides." I don't think you'd ever use "face" in this way in just plain old talk....

On the other hand, most English-speakers will understand "vertex" and "face" in a geometrical context, even if they don't use them in everyday speech. When dealing with three-dimensional objects, "side" can be ambiguous in a way that "edge" and "face" aren't. Anthony Argyriou 00:13, 27 June 2009 (UTC)
