WebA face is a flat surface on a solid, and edges are the lines at which faces meet, and a vertex is the point at which when three or more edges meet. A sphere has no flat surfaces, so it has no faces. Since it doesn't have faces, it can't have edges, or vertices. Comment ( 10 votes) Upvote Downvote Flag more Show more...
