Enter 2 of the 3 below


<-- Vertices
<-- Faces
<-- Edges
  

A planar graph has:

12 edges and 6 faces.

Calculate the number of vertices 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 v

Rearrange Eulers Formula

v = e - f + 2

v = 12 - 6 + 2

v = 6 + 2

v = 8


You have 2 free calculationss remaining



What is the Answer?
v = 8
