Theorem 2: An undirected graph has an Euler circuit iff it is connected and has zero vertices of odd degree. 5 to construct an Euler cycle. The above proof only shows that if a graph has an Euler cycle, then all of its vertices must have even degree. It does not, however, show that if all vertices of a (connected) graph have even degrees then it must have an Euler cycle. The proof for this second part of Euler’s theorem is more complicated, and can beEuler described his work as geometria situs—the “geometry of position.” His work on this problem and some of his later work led directly to the fundamental ideas of combinatorial topology, which 19th-century mathematicians referred to as analysis situs—the “analysis of position.” Graph theory and topology, both born in the work of ... The Königsberg bridge problem asks if the seven bridges of the city of Königsberg (left figure; Kraitchik 1942), formerly in Germany but now known as Kaliningrad and part of Russia, over the river Preger can all be traversed in a single trip without doubling back, with the additional requirement that the trip ends in the same place it began.
