Solution Each person will be represented by a vertex and each friendship will be represented by an edge.

Think of the top row as the houses, bottom row as the utilities. We are really asking whether it is possible to redraw the graph below without any edges crossing except at vertices. For now, notice how we would ask this question in the context of graph theory. Is it possible to do this without any of the utility lines crossing? Each of three houses must be connected to each of three utilities. That is, two vertices will be adjacent there will be an edge between them if and only if the people represented by those vertices are friends. Each person will be represented by a vertex and each friendship will be represented by an edge.

It turns out that Al and Cam are friends, as are Bob and Dan. But first, here are a few other situations you can represent with graphs. We will return to the question of finding paths through graphs later. This was the great insight that Euler had. All that matters is which land masses are connected to which other land masses, and how many times. It does not matter how big the islands are, what the bridges are made out of, if the river contains alligators, etc. The nice thing about looking at graphs instead of pictures of rivers, islands and bridges is that we now have a mathematical object to study. When two vertices are connected by an edge, we say they are adjacent. Graphs are made up of a collection of dots called vertices and lines connecting those dots called edges. Pictures like the dot and line drawing are called graphs. Is it possible to trace over each line once and only once without lifting up your pencil, starting and ending on a dot? There is an obvious connection between these two problems. As time passed, a question arose: was it possible to plan a walk so that you cross each bridge once and only once? Euler was able to answer this question.ДЄre you? Graph Theory is a relatively new area of mathematics, first studied by the super famous mathematician Leonhard Euler in Since then it has blossomed in to a powerful tool used in nearly every branch of science and is currently an active area of mathematics research. The bridges were very beautiful, and on their days off, townspeople would spend time walking over the bridges. The islands were connected to the banks of the river by seven bridges as seen below.
