It is a vertex and its plural is vertices
1 corner,0 vertices and 0 edges * * * * * A vertex is the same as a corner, so a cone has 1 vertex. It has two faces: one circular and one curved. It has one edge where the two faces meet.
A dodecahedron has 12 regular pentagonal faces, 20 vertices, and 30 edges. Three faces meet at each vertex.
Three edges meet at each vertex.
Edges meet at a vertex.
As many edges that its base has
No. For example, a cube is a polyhedron and 3 edges meet at each vertex.
A vortex is an area of circular fluid flow in fluid dynamics and no edges meet there. A vertex is a corner of a geometric shape and there can be two or more edges meeting at a vertex. There is no upper limit to the number of edges.
A vertex is when 2 edges meet and make a curved line.
