Explanation This should be shown for the figure, given below if a route that crosses each edge is present just once. Explanation will also have to be given. An Eulerian circuit is a circuit that traces each edge of the graph and anEulerian trail passes through each edge once. If a graph has anEulerian circuit, it must also be a graph connected to the degree of the corner. AEulerian mark is present in a connected graph if two vertices are of odd degree and other corners are of equal degree. To be able to traverse all edges in a trail, the graph either consists of anEulean circuit or a Eulerian trail. In this problem we do not cross edges, but have to cross edges. So we label the six regions in this figure as shown below: A pseudograph is constructed where the vertices represent these regions and each edge indicates the crossing of an edge in the figure above when a passage passes between regions...

The existence of any sort route in and around the figure that crosses every edge exactly once.

Solution Summary: The author explains that a pseudograph has 4 odd vertices and 2 even ones, so no route exists for the figure.
