We are given a graph and we are asked to determine if the graph is bipartite.
00:09
So to do this, we'll use theorem of four from the book.
00:16
So i have here a graph, vertices, a, b, c, d, e, and f.
00:22
And to answer the question of whether it's bipartite, suppose that i color, without loss of generality, i color vertex a, red.
00:33
Then we see that if i have to color every adjacent edge to a, if you're adjacent vertex to a blue, i need to color b blue, and you need to color d blue, and i need to color e blue...
