(a) Prove that a vertex u is a cut vertex if and only if there
are vertices v and w, both different from u, such that every path
between v and w passes through u.
(b) Prove that an edge in a simple graph is a cut edge if and
only if this edge is not part of any circuit in the graph.
f d (b) How many automorphisms does Chave? Explain your answer. (Hint: try rotating and flipping C, to see the symmetries). 3 (2pta) (a) Prove that a vertex u is a cut vertex if and only if there are vertices and w, both different from such that every path between and w passes through w. (b) Prove that an edge in a simple graph is a cut edge if and only if this edge is not part of any circuit in the graph. 4 (a) (Ipt) Find all cut vertices and cut edges of this graph: b
are vertices v and w, both different from u, such that every path
between v and w passes through u.
(b) Prove that an edge in a simple graph is a cut edge if and
only if this edge is not part of any circuit in the graph.
