A cone has 1 vertex , which is the pointed tip called the apex
. It also has 1 edge, which is the circular boundary of its base, and 1 face plus 1 curved surface
. In summary:
- Vertices: 1 (the apex)
- Edges: 1 (the circular edge at the base)
- Faces: 1 flat face (the base) and 1 curved surface
This is the standard geometric definition used in most educational contexts.
