3 It's consisting of vertices and edges that connect these vertices. Its have different types that differ with respect to the kind and number of edges that can connect pair of vertices..

4  Set V = v(G) whose element are called vertices, points or nodes of G..  Set E =E(G) of unordered pairs of distinct vertices called edges of G استغفر الله وأتوب إليه

5 1..Simple of graph: G(V,E)consist of V, a nonempty set of vertices and E, a set of unordered pairs of distinct elements of V called edges.. ab c d e1 e2 e3 e4 e5

6 a c BdBd b e1 e2 e3 e4 e5

7 AcAc b d a c e1 e2 e3 e4 e8 e7 e5e6 e9

8 Fine the components of the short and represent to matrix…and what it type of it ? A b C d

9 G=(V,E) V=[a,b,c,d] E=[(a,b),(b,c),(b,d),(a,c),(c,d),(a,d)] |V|=4 vertices.. |E|=6 edges.. Deg(a)=3 Deg(b)=3 Deg(c)=3 Deg(d)=3

10 a,b,c,a length =3 d,b,c,d length =3 a,b,c,d,a length =4 Matrix: a b c d a b c d Type of graph :{simple graph}..
