This graph is not an Euler circuit because not all edges have been covered. 4. In order for a graph to have an Euler circuit‚ all vertices must have even valence. Graph II is an Euler circuit because all vertices have even valence. 5. In order for a circuit to be an Euler circuit‚ each path must be covered once and only once. Since
