A cone has:
- 1 face, which is the curved surface that wraps around the cone. If we're referring to the traditional definition of a "face" as a flat surface, then strictly speaking, a cone has no flat faces. However, the base of the cone is typically considered a face in common language, even though geometrically it's not part of the cone's lateral surface.
1 edge, which is the circular boundary where the base meets the curved surface. Again, in strict geometrical language, an edge is a line where two flat surfaces meet, so some might argue a cone technically has no edges since its surface is curved. But in common discussions, the perimeter of the base is often referred to as the edge.
1 vertex, which is the apex or point of the cone.
How many faces, edges, and vertices does a cone have?(2 points)
