So ‘c’ is a pendent …
In formal terms, a directed graph is an ordered pair G = (V, A) where • V is a set whose elements are called vertices, nodes, or points; • A is a set of ordered pairs of vertices, called arcs, directed edges (sometimes simply edges with the corresponding set named E instead of A), arrows, or directed lines.
