The Konigsberg Bridge Problem

This is a picture of the town of Konigsberg.

(It is now called Kalliningrad and is in the Russian Federation – can you find it on a map?).

There is a famous mathematical problem about the town of Konigsberg.

This is the problem:

Show how you can walk over all of the bridges.

You must cross each one only once.







Can it be done ? Try to explain how it can be done OR why it cannot be done !

A mathematician called Leonhard Euler first solved the problem mathematically. His ideas led to the development of a branch of mathematics called topology.
