Euler's puzzle  
« on: Apr 20th, 2010, 8:15pm »

Say one can draw three houses, a gas company, an electric company, and a water works company. Also say that one can draw a line from each of the companies to each of the houses. How can one do this without crossing any two lines or combining more than one line at one or more points.  I have spent a great many hours attempting to discover it trying to use Euler's theorem.
 
thanks for help in advance

Even I can remember that K3,3 is non-planar.
