Introduction to Graph Theory, By Douglas B.West/
Teaching Outlines
Concept #1 Representation of a Graph
Learning objectives
- To define what is node.
- to define what is arc
- To define what is Region
- To represent a Graph with node, Arc and Regions
Notes for teachers
Here we should remember in any Graph a point which is not represented by letter cannot be considered as NODE
Activities
Activity #1 Introduction to Graphs
Activity #2 Graph Theory
Concept #2 Types of Graphs
Learning objectives
- To identify Plane Graph
- To identify Non-Plane Graph
Notes for teachers
These are short notes that the teacher wants to share about the concept, any locally relevant information, specific instructions on what kind of methodology used and common misconceptions/mistakes.
Activities
Activity No #1
Construction of regular polyhedrons
Activity No #2
Concept #3 Eulers formula for graph
Learning objectives
- Generalization of Euler's formula
- Verification of Euler's formula for Networks
Notes for teachers
These are short notes that the teacher wants to share about the concept, any locally relevant information, specific instructions on what kind of methodology used and common misconceptions/mistakes.
Activities
Activity No #1

Activity No #2 Activity on verification of eulers formula
Concept # 4 Traversibility of a graph
Learning objectives
- To Identify even order node
- To Identify Odd order node
- Condition for Traversibility
- Condition for Non- Traversibility of Graph
Notes for teachers
These are short notes that the teacher wants to share about the concept, any locally relevant information, specific instructions on what kind of methodology used and common misconceptions/mistakes.

Hints for difficult problems
Statement : The Königsberg bridge problem : if the seven bridges of the city of Königsberg (left figure; Kraitchik 1942), formerly in Germany but now known as Kaliningrad and part of Russia, over the river Preger can all be traversed in a single trip without doubling back, with the additional requirement that the trip ends in the same place it began.
