Base case: Forn= 3 the polygon is a triangle Every vertex in a triangle has zero non-adjacent vertices(since all the vertices are all adjacent to each other) Therefore there are 0 diagonals and so the cardinalityof any set containing non-intersecting diagonals must be 0 Since 0 n3P(3) holds |
What are adjacent vertices?
- 28. 16 Theory of Automata, Formal Languages and Computation Adjacent vertices: A pair of vertices that determine an edge are “adjacent” vertices. In the graph shown above, vertex ‘e’ is an “Isolated vertex”, ‘a’ and ‘b’ are adjacent vertices, vertices ‘a’ and ‘d’ are not adjacent.
Which vertices have no connectivity between each other?
- Here, the vertex 'a' and vertex 'b' has a no connectivity between each other and also to any other vertices. So the degree of both the vertices 'a' and 'b' are zero. These are also called as isolated vertices. In a graph, two vertices are said to be adjacent, if there is an edge between the two vertices.
What are adjacent vertices in an undirected graph called?
- De?nition 1. Two vertices u, v in an undirected graph G are called adjacent (or neighbors) in G if there is an edge e between u and v.
