let be the degree of the vertex then either or you should be able to easily finish the proof now.
thank you for this...just little bit more
well i see that you are making two sets and one less then other, but how are you supposed to put that in to proof language...

the number of elements of both sets is so we have vertices and possible values for the degrees of the vertices. thus at least two vertices must have the same degree.
