  1. There are two sets of mathematical explanations about vertices and edges.
    1. solids (polyhedrons)
    Each "corner" of a solid is a vertex, and the intersection of two surfaces (faces) make and edge.
    For example, a cube has 8 vertices, 12 edges, and 6 faces.
    The Euler formula relates these three quantities:
    V + F = E + 2

    2. Graph theory
    A graph is a collection of vertices and edges, or G={V,E} where V is a set of vertices, and E is a set of edges. An edge joins two vertices, and is defined as e=(v1,v2).
    If this is the definition you need, or you need additional information, post.
