A point where two or more straight lines meet. In graph theory, an Eulerian trail (or Eulerian path) is a trail in a finite graph that visits every edge exactly once (allowing for revisiting vertices). Edges cannot be repeated. In order to do that, she will have to duplicate some edges in the graph until an Euler circuit exists. A graph will contain an Euler circuit if all vertices have even degree. Give the number of edges in each graph, then tell if the graph has an Euler path, Euler Circuit, or neither. These can have repeated vertices only. Rather than finding a minimum spanning tree that visits every vertex of a graph, an Euler path or circuit can be used to find a way to visit every edge of a graph once and only once. There is also a mathematical proof that is used to find whether a Eulerian Circuit is possible in the graph or not by just knowing the degree of each vertex in the graph. 2. if a graph has no odd vertices, it has at least one euler circuit 3. if a graph has more than two odd vertices, it has no euler paths or euler cicuits .
