In an undirected planar graph
A simple graph is called maximal planar if it is planar but adding any edge (on the given vertex set) would destroy that property. All faces (including the outer one) are then bounded by three edges, explaining the alternative term plane triangulation. The alternative names "triangular graph" or "triangulated graph" have also been used, but are ambiguous, as they more commonly refer to the li… Web20-5 Inserting and querying vertices in planar graphs A planar graph is an undirected graph that can be drawn in the plane with no edges crossing.

Euler proved that every planar graph has ∣E ∣ < 3∣V ∣. Consider the following two operations on a planar graph G : - INSERT (G,v, neighbors) inserts a new vertex v into G, where neighbors is ...
WebMar 16, 2024 · Let G be a simple undirected planar graph on 10 vertices with 15 edges. If G is a connected graph, then the number of bounded faces in any embedding of G on the plane is equal to Q5. The line graph L (G) of a simple graph G is defined as follows: There is exactly one vertex v (e) in L (G) for each edge e in G.
