In this video we prove the following Euler's Formula for Plane Graph and a generalisation to an arbitrary plane graph.
If G is a connected plane graph on n vertices, m edges and r regions, then n-m+r= 2.
If G is a plane graph on n vertices, m edges and r regions with c(G) connected components , then n-m+r= 2+c(G).
