Question 16. A maximal plane
graph is a plane graph G = (V, E) with n ≥ 3 vertices such that if
we join any two non-adjacent vertices in G, we obtain a non-plane
graph. (a) Draw a maximal plane graphs on six vertices. (b) Show
that a maximal plane graph on n points has 3n − 6 edges and 2n − 4
faces. (c) A triangulation of an n-gon is a plane graph whose
infinite face boundary is a convex n-gon and all of whose other
faces are triangles. How many edges does a triangulation of an
n-gon have?

Let G -(V, E) be a graph. The complementary graph G of G has vertex set V. Two vertices are adjacent in G if and only if they are not adjacent in G. (a) For each of the following graphs, describe its complementary graph: (i) Km,.ni (i) W Are the resulting graphs connected? Justify your answers. (b) Describe the graph GUG. (c) If G is a simple graph with 15 edges and G has 13 edges, how many vertices does...
Let G (V, E) be a directed graph with n vertices and m edges. It is known that in dfsTrace of G the function dfs is called n times, once for each vertex It is also seen that dfs contains a loop whose body gets executed while visiting v once for each vertex w adjacent to v; that is the body gets executed once for each edge (v, w). In the worst case there are n adjacent vertices. What do...
