How many edges does a complete graph have.

That is, a graph is complete if every pair of vertices is connected by an edge. Since a graph is determined completely by which vertices are adjacent to which other vertices, there is only one complete graph with a given number of vertices. We give these a special name: \(K_n\) is the complete graph on \(n\) vertices. A complete digraph is a directed graph in which every pair of distinct vertices is connected by a pair of unique edges (one in each direction). [1] Graph theory itself is typically dated as beginning with Leonhard Euler 's 1736 work on the Seven Bridges of Königsberg.Complete Weighted Graph: A graph in which an edge connects each pair of graph vertices and each edge has a weight associated with it is known as a complete weighted graph.
