Euler's Characteristic Formula V - E + F = 2 Euler's Characteristic Formula states that for any connected planar graph, the number of vertices (V) minus the number of edges (E) plus the number of faces (F) equals 2.

Criteria for Euler Path. Theorem A connected graph contains an Euler path and not an Euler circuit if and only if it has exactly 2 vertices of odd degree.. Proof Suppose a connected graph G containing an Euler Path P. For every vertex v, other than starting and ending vertex, the path P must enter and exit the vertex the same number of time.In simple words, the degree of v should be even.

A Polyhedron is a closed solid shape having flat faces and straight edges. This Euler Characteristic will help us to classify the shapes. Let us learn the Euler’s Formula here. Surprisingly, every non-planar graph arises this way, a result called Kuratowski's Theorem. Euler's formula can also be used to prove results about planar graphs. Activity30 Prove that any planar graph with v v vertices and e e edges satisfies e ≤ 3v−6. e ≤ 3 v − 6.

It follows from Euler's formula that every self-dual graph with n vertices has exactly 2n − 2 edges. Every simple self-dual planar graph contains at least four vertices of degree three, and every self-dual embedding has at least four triangular faces.

Euler’s formula states that the sum of faces and vertices with the difference of edges must be equal to 2.

The Euler characteristic can be defined for connected plane graphs by the same formula as for polyhedral surfaces, where F is the number of faces in the graph, including the exterior face. The Euler characteristic of any plane connected graph G is 2.
