Solve the problem.The floor plan of a building is shown in the figure below. Starting outside, is it possible to walk through each door exactly once, and end up back outside? Justify your answer.
What will be an ideal response?
No. Two of the rooms have an odd number of doors (so two of the vertices in the graph representing this floor plan have an odd number of edges), and thus there is no Euler circuit for the building.
