A cylinder has zero (0) vertices.
A vertex, in geometric terms, is a point where two or more lines or edges meet. Essentially, it's a corner. Think of a cube or a pyramid; those shapes have vertices.
A cylinder, however, is defined by two parallel circular bases connected by a curved surface. Because a cylinder is made up of curved surfaces and circular faces, it lacks any sharp corners or points where edges meet. Therefore, it doesn't have any vertices. The curved nature of its surface prevents the formation of vertices.
