A simple graph is triangle-free when it has no simple cycle of length three.
(a) Prove for any connected triangle-free planar graph with v>2 vertices and e edges. e < 2v - 4.
Hint: Similar to the proof that e < 3v - 6.
(b) Show that any connected triangle-free planar graph has at least one vertex of degree three orless.
(c) Prove by induction on the number of vertices that any connected triangle-free planar graph is 4-colorable.
Hint: use part b
