Euler's formula is:V + F - E= 2V = the number of vertices, each point where three or more edges intersect.E = the number of edges, each intersection of the faces.F = the number of faces, each plane polygon.
triangle
Edges join two vertices. Three or more edges meet at a vertex (it could be two if not in a polyhedron).
eight * * * * * A triangular pyramid has six edges: three edges that form the triangular base and then three more edges going up from each vertex of the base to the apex (peak) of the pyramid.
Vertex.
That is the Vertex
edges are the intersection of faces in a three dimentional figure: a cube has 12 edges

It is the intersection of two planes or the line joining two vertices.
