graphs in graph theory stands up on some basic terms such as point, line, vertex, edge, degree of vertices, properties of graphs, etc. Here, in this chapter, we will cover these fundamentals of graph theory. Point A point is a particular position in a one-dimensional, two-dimensional, or three-dimensional space.
This tutorial offers a brief introduction to the fundamentals of graph theory. Written in a reader-friendly style, it covers the types of graphs, their properties, trees, graph traversability, and the concepts of coverings, coloring, and matching.

For two quarters of Combinatorics, take Math 154 and 184 in either order. Math 158 and 188: More advanced/theoretical than Math 154 and 184.
Given a graph G,itsline graph or derivative L[G] is a graph such that (i) each vertex of L[G] represents an edge of G and (ii) two vertices of L[G] are adjacent if and only if their corresponding edges share a common endpoint (‘are incident’) in G (Fig. ??).
1. Draw Cn for n = 0; 1; 2; 3; 4; 5. Soln. These look like loop graphs, or bracelets. The n = 0 graph is empty, the n = 1 is a single vertex with a loop on it, and n = 2 is two vertices with a double edge between. n = 3 is a triangle, n = 4 is a square, etc. 2. Is Cn simple? Soln. For n 3, yes. I suppose technically for n = 0 too. But n = 1 has.

Graph Theory, Exam 1 Practice Sheet. 1. Suppose G is a simple, connected graph and e is an edge in G. Show that there is a spanning tree of G containing e. 2. Recall that a edge e in a connected graph G is bridge if and only if G e is disconnected.
