Presentation Transcript. Euler Paths • An Euler path is when a trail on a graph visits each edge exactly once. • An Euler path must have an odd amount of degrees, and if the Euler is connected and has an even amount then it has at least one Euler circuit. • If you can start at a vertex and move to every single edge, it is an Euler path.
