Prove the followings:
a) the sum of the degrees of the vertices of G is twice the number of edges
b) If W is a u-v walk joining two distinct vertices u and v, then there is a path joining u and v contained in the walk using the principles of mathematical induction
c) A connected graph G is Eulerian if and only if the degree of each of its vertices is even.
d) If G is a connected planar (p,q)-graph, then the number r of the regions of G is given by r = q - p +2
