text: A directed edge is often called an arc.
text: Similar notions may be defined for directed graphs, where each edge (arc) of a path or cycle can only be traced in a single direction (i.e., the vertices are connected with arrows and the edges traced "tail-to-head").
text: Edges are sometimes referred to as arcs.
text: Edges may be directed or undirected; undirected edges are also called lines and directed edges are also called arcs or arrows.
text: This latter type of graph is called a directed graph and the edges are called directed edges or arcs.
text: When the edges in a graph have a direction, the graph is called a directed graph or digraph, and the edges are called directed edges or arcs.
text: A Digraph is a graph $D$ that contains directed edges (also called arcs) instead of regular edges.
