4 cards from this section. Quick, good the night before a test.
Define what a vertex and an edge are.
Think of a graph as a network of points.
What is the degree of a vertex?
Count how many edges touch a vertex.
What does Euler's Theorem state?
Think about the implications for vertex counts.
True or False: A graph can have any number of odd-degree vertices.
Recall Euler's theorem.
Given a graph with 5 vertices and 5 edges, demonstrate Euler's theorem by identifying vertices with odd and even degrees.
What must the total reflect about odd counts?
Devise a simple graph that satisfies Euler's theorem with at least 6 vertices.
Sketch different configurations!
