Euclid’s Axioms. Before we can write any proofs, we need some common terminology that will make it easier to talk about geometric objects. These are not particularly exciting, but you should already know most of them: A point is a specific location in space. Points describe a position, but have no size or shape themselves.

The town of Königsberg straddles the Pregel River. It was formerly in Prussia, but is now known as Kaliningrad and is in Russia. Königsberg was situated close to the mouth of the river and had seven bridges joining the two sides of the river and also an island and a peninsula. Answer to the diagrams table:If you represent the bridges and islands of Konigsberg by a graph, then the graph has 4 nodes and all 4 nodes have odd degree. To make an Eulerian circuit possible then you have to add two bridges. However, to make an Eulerian path possible (where the starting node and the end node do not have to be the same) you only have to add one bridge.The city of Konigsberg, Northern Germany has a significant role in Euler's life and in the history of graph theory.
