What is an Euler tour?

• A path that starts and ends at different vertices

• A path that starts and ends at the same vertex, visiting every edge once

• A path that visits every vertex once

• A path that visits every edge twice

Why is it impossible to complete an Euler tour on a complete graph with four vertices?

• There are too many vertices

• Each vertex has an odd number of edges

• The graph is not connected

• The edges are too long

What is an Euler trail?

• A path that visits every vertex once

• A path that starts and ends at the same vertex, visiting every edge once

• A path that starts and ends at different vertices, visiting every edge once

• A path that visits every edge twice

What is the key difference between an Euler tour and an Euler trail?

• An Euler trail starts and ends at different vertices

• An Euler tour starts and ends at the same vertex

• An Euler trail visits every edge twice

• An Euler tour visits every vertex once
