Answer
In the geometry of graphs, if you can trace a graph without lifting your pencil from the paper and without tracing an edge more than once, then the graph is called traversable.
Work Step by Step
Swiss mathematician Leonhard Euler introduced a new type of geometry to design city streets, analyze traffic patterns and discover the most effective routes for public transportation known as Graph Theory. According to the graph theory, if the path of the graph (a route in a city) is covered by crossing all the edges (the bridges in a city) exactly once and without stopping, the graph is traversable.
Thus, the graph is called traversable.
