How many edges are in a complete graph?
A complete graph has an edge between any two vertices. You can get an edge by picking any two vertices. So if there are n vertices, there are n choose 2 = (n2)=n(n?1)/2 edges.
What is the size of a complete graph?
You might have observed that number of edges in a complete graph is n(n?1)2. This is the maximum achievable size for a graph of order n as you learnt in Order and Size.
How many edges can a complete graph K5 has?
K5: K5 has 5 vertices and 10 edges, and thus by Lemma 2 it is not planar.
The symbol used to denote a complete graph is KN. In each complete graph shown above, there is exactly one edge connecting each pair of vertices. There are no loops or multiple edges in complete graphs. Complete graphs do have Hamilton circuits.
