Bipartite graphs: Graphs in which nodes decompose into two groups such that there are edges only between these groups. Hypergraphs can be represented as a bipartite graph. A tree is a connected (undirected) graph with no cycles. In a tree, there is a unique path between any two nodes. A connected graph is a tree if and only if it has n 1 edges. 11Order of a graph is the number of vertices in the graph.. Size of a graph is the number of edges in the graph..

Given an undirected graph, a matching is a set of edges, such that no two edges share the same vertex. In other words, matching of a graph is a subgraph where each node of the subgraph has either zero or one edge incident to it. A vertex is said to be matched if an edge is incident to it, free otherwise.In the following example, graph-I has two edges ‘cd’ and ‘bd’. Its complement graph-II has four edges. Note that the edges in graph-I are not present in graph-II and vice versa. Hence, the combination of both the graphs gives a complete graph of ‘n’ vertices.
