Construction of a regular nonagon
A regular nonagon can be constructed using a compass and a marked ruler ( or Geogebra tools that simulate a compass and a marked ruler in my case)
This type of construction is not limited to the nonagon , the though behind it can be applied to to all 6n+3 polygons (not the triangle) , I am pretty sure.
