Draw, if possible, two different planar graphs with the same number of vertices, edges, and faces. Draw, if possible, two different planar graphs with the same number of vertices and edges, but a different number of faces.The tetrahedral graph (i.e., ) is isomorphic to , and is isomorphic to the complete tripartite graph. In general, the -wheel graph is the skeleton of an -pyramid. The wheel graph is isomorphic to the Jahangir graph. is one of the two graphs obtained by removing two edges from the pentatope graph, the other being the house X graph.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.

There are a number of measures characterizing the degree by which a graph fails to be planar, among these being the graph crossing number , rectilinear crossing number , graph skewness ... In graph theory, an adjacency matrix is nothing but a square matrix utilised to describe a finite graph.

A (simple) graph in which every vertex is adjacent to every other vertex, is called a complete graph. If this graph has \(n\) vertices, then it is denoted by \(K_n\). The notation \(K_n\) for a complete graph on \(n\) vertices comes from the name of Kazimierz Kuratowski, a Polish mathematician who lived from 1896–1980. From [1, page 5, Notation and terminology]: A graph is complete if all vertices are joined by an arrow or a line. A subset is complete if it induces a complete subgraph. A complete subset that is maximal (with respect to set inclusion) is called a clique. So, in addition to what was described above, [1] says that a clique needs to be maximal..
