Best Answer: a cone has Facse: 2 (the base and the slanted surface) Edges: 1 (the joining of base with the slanted surface) Corners: 1 (the apex) You just need to visualize the cone. Source(s): TJ Â· 9 years ago.
Vertices, Edges and Faces. A vertex is a corner. An edge is a line segment that joins two vertices. A face is an individual surface. Let us look more closely at each of those: A vertex (plural: vertices) is a point where two or more straight lines meet. It is a Corner. This tetrahedron has 4 vertices. An edge is a line segment that joins two vertices on the boundary or where faces meet. For a polyhedron they are where two faces meet. This tetrahedron has 6 edges. For a polygon they are on the boundary. Sometimes called sides.
