Abstract— The Study of planar graphs necessarily involves the topology of the plain. It is especially relevant in the study of planar graphs are those which deal with the curves. In terms of Jordan curves it is continuous non self intersecting curve and whose origin and terminus coincide. In general properties of Jordan curves come into play in planar graph theory. If J be the Jordan Curve in the plan the remaining of the plane indicates two disjoint open sets called interior and exterior of Jordan(J). In this Application we can observe that the Jordan(J)= Int.J Ո Ext.J. Jordan curve theorem states that the line joining a point in Int.J to a point in Ext.J must meet J in some point in its planar graph.
Keywords—toplogy, Jordan curves, Self intersecting curve, interior and exterior, coincide.
