A cylinder has two edges.
According to the provided reference, a cylinder is a 3-dimensional geometric shape with specific characteristics:
- It has two circular faces at the top and bottom.
- It features one curved surface connecting the two faces.
- Importantly, it has two edges where the circular faces meet the curved surface.
- It has zero vertices (corners).
Understanding Edges in Geometry
In geometry, an edge is a line segment where two faces of a three-dimensional shape meet. For a cylinder, these edges are the circular boundaries of its top and bottom faces.
Cylinder Properties
| Property | Description |
|---|---|
| Faces | 2 circular faces, 1 curved surface |
| Edges | 2 |
| Vertices | 0 |
To clarify, the edges are the circular lines that run around the top and bottom of the cylinder. They are not straight lines, but circular curves.
Therefore, a cylinder has only two edges, as confirmed by the reference.
