Odd and Even Vertices

Dear Dr. Math,

We have a question.  We are tracing networks and trying to trace 
them without crossing a line or picking up our pencils. We don't 
understand about what odd or even vertices are.  How can we know if a 
vertex is odd or even?

A vertex is odd if an odd number of arcs is attached to the vertex; 
it is even if an even number of arcs is attached to the vertex.
