Question
Problem 3: Below are four graphs. Determine the unknowns or requirements for each graph. If the
requirement is a trace or traversal of a walk, trail, path, cycle, tour, or circuit and the way on how the
answer is suppose to be written is not stated; state your answer by listing the sequence of the Nodes /
Vertices that shows the trace or traversal (see the example below).

a.
Example 107:
X
Requirements:
G₁
B
b
The trail d-a-b-c-d-b of G₁ is an Euler trail. G₁ has a tour d-a-b-c-d-b-d but it is not
an Euler tour. G₂ has an Euler tour B-A-C-E-D-C-B hence is an Euler graph.
