= Teaching Outlines =

Learning objectives

 * 1) To define what is node.
 * 2) to define what is arc
 * 3) To define what is Region
 * 4) 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

= 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.
