The number of n edges is the length of the path. A path of length 0 consists of a single vertex. When G is simple, a path is a sequence of vertices. COMPLETE GRAPH: A complete graph on n vertices is a simple graph in which each vertex is connected to every other vertex and is denoted by K n (K n means that there are n vertices). The following are complete graphs K 1, K 2,K 3, K 4 and K 5.

In every graph, the sum of the degrees of all vertices equals twice the number of edges. ... 1, 3, 5, No such graphs exist * Provided the graph is connected. This cannot be a tree. Each degree 3 vertex is adjacent to all but one of the vertices in the graph. Thus each must be adjacent to one of the degree 1 vertices (and not the other). That means both degree 3 vertices are adjacent to the degree 2 vertex, and to each other, so that means there is a cycle.
