Planar Graph (Self Doubt)
This is a graph ? Is it planar or not ? As per definition of planar graph it can be drawn in such a way that no edges cross each other. other theorems are if a connected simple graph is planar→ e<=3n-6 if a connected simple graph is planar → ... for planar graph not meet if the graph is planar but Now if i draw i dont intersect any edges .,which show it is planar
