Graph theory (the precursor of modern network theory) was invented by the great mathematician Leonhard Euler. In 1735 he was able to prove that it was not possible to walk through the city of Königsberg (now Kaliningrad) crossing each of its seven bridges only once—because of the layout of islands in the Pregel River (fig. 1).

The Bridges of Koenigsberg: Euler 1736 “Graph Theory ” began in 1736 Leonard Euler – Visited Koenigsberg – People wondered whether it is possible to take a walk, end up where you started from, and cross each bridge in Koenigsberg exactly once – Generally it was believed to be impossible

The Konigsberg bridges have the interesting property that adding or deleting a bridge between any two landmasses will allow an Eulerian path. Indeed, adding or deleting a bridge will change the parity of the degrees of two of the four vertices of the associated graph, which will make them both even. ...Question: Konigsberg bridges The Konigsberg bridge puzzle is universally accepted as the problem that gave birth to graph theory. It was solved by the great Swiss-born mathematician Leonhard Euler (1707 - 1783). The problem asked whether one could in a single stroll, cross all seven bridges of the city of Konigsberg exactly once and return to a starting point.Dilations. So far, we have just looked at ??? transformations. Now let’s think about one that is not: a dilation changes a shape’s size by making it larger or smaller.
