The next theorem gives necessary and sufficient conditions o f a graph having an Eulerian tour. Euler’s Theorem: An undirected graph G=(V,E)has an Eulerian tour if and only if the graph is connected (with possible isolated vertices) and every vertex has even degree. Proof (=⇒): So we know that the graph has an Eulerian tour.

Eulerian path - Wikipedia

https://en.wikipedia.org/wiki/Euler_cycle

Oct 02, 2003 · Euler proved that a necessary condition for the existence of Eulerian circuits is that all vertices in the graph have an even degree, and stated without proof that connected graphs with all vertices of even degree have an Eulerian circuit. The first complete proof of this latter claim was published posthumously in 1873 by Carl Hierholzer.

Definition A Euler tour of a connected, directed graph G = (V, E) is a cycle that traverses each edge of graph G exactly once, although it may visit a vertex more than once. In the first part of this section we show that G has an Euler tour if and only if in-degrees of every vertex is equal to out-degree vertex.

In the graph below, vertices A and C have degree 4, since there are 4 edges leading into each vertex. B is degree 2, D is degree 3, and E is degree 1. This graph contains two vertices with odd degree (D and E) and three vertices with even degree (A, B, and C), so Euler’s theorems tell us this graph has an Euler path, but not an Euler circuit.

A connected undirected graph has an Euler cycle each vertex is of even degree. Proof. Each time the path passes through a vertex it contributes two to the vertex's degree, except the starting and ending vertices. If the path terminates where it started, it will contrib-ute two to that degree as well.
