This graph will have a Euler's Circuit

• True
• False

How do we quickly determine if a graph will have a Euler's Circuit? 

• All even degree verticies
• Exactly 2 odd degree verticies
• Every Vertex will be used once
• I have no clue

Is the following graph connected or disconnected? Explain why or why not.

• Connected because all vertices are even.

• Connected because one can get from one vertex to every other vertex on the graph

• Disconnected because all vertices are even

• Disconnected because one can NOT get from one vertex to every other vertex.
