The following graph is an example of a bipartite graph-. Here, The vertices of the graph can be decomposed into two sets. The two sets are X = {A, C} and Y = {B, D}. The vertices of set X join only with the vertices of set Y and vice-versa. The vertices within the same set do not join. Therefore, it is a bipartite graph.This is because our definition for a graph says that the edges form a set of 2-element subsets of the vertices.

A graph G which is connected but not 2-connected is sometimes called separable. Analogous concepts can be defined for edges.
