Calculate the number of edges using
Eulers Formula for Planar Geometry

A planar graph has:

4 faces and 5 vertices.

Calculate the number of edges using

Eulers Formula for Planar Geometry

Eulers Formula Drawing

Draw a planar graph

Include zero edge intersections

with v vertices, e edges and f faces

Eulers Formula

v - e + f = 2

Calculate e

Rearranging Eulers Formula

e = v + f - 2

e = 5 + 4 - 2

e = 9 - 2

e = 7
