On a graph that represents six cities and the roads between them, the valence of
vertex A is 4. What does this mean in real world terms?
Ans:
2. Which of the graphs below are connected? Explain
Ans:

4. Which of the graphs below have Euler circuits? Explain.
Ans:
5. Consider the path represented by the sequence of numbered edges on the graph
below. Why does the path notrepresent an Euler circuit?

7. In order to eulerize the graph below, give the fewest number of edges that need to be
added or duplicated? Explain.
Ans:
8. Which of the graphs shown below gives the best eulerization of the given graph? (In
the graphs below, added edges are denoted with zig-zag lines.) Explain.
Ans:
9. Give three real world applications in which a worker would want to find an Euler circuit
on a street network.
Ans:
10. Why would a city street department want its snow plow operator’s path to follow an
Euler circuit if possible?
