What is the usual number of edges meeting at a vertex?

Answer 1

In most common geometric shapes, such as polyhedra, the usual number of edges meeting at a vertex is typically three or more. For example, in a tetrahedron, four edges meet at each vertex, while in a cube, three edges converge at each vertex. In general, the number can vary depending on the specific shape or structure being considered. However, in polygons, specifically, at least three edges must meet at a vertex.
