A complete graph is a type of undirected graph in which every pair of distinct vertices is connected by a unique edge. This means that for a complete graph with 'n' vertices, there are $$rac{n(n-1)}{2}$$ edges, as each vertex is directly connected to every other vertex. The complete graph is denoted as $$K_n$$, where 'n' represents the number of vertices. Complete graphs are significant in various areas like graph coloring and graph representations because they serve as a basis for understanding more complex structures and properties.
congrats on reading the definition of complete graph. now let's actually learn it.
