With turtle graphics it is quite easy to construct regular polygons in a recursive manner.

It is possible to play around with this example: In the last line of the input window there is the command


The meaning of the parameters is

  • 5: number of vertices of the regular polygon,
  • 100: length of a side of the initial polygon,
  • 0.4: shrink factor from one level to the next,
  • 5: number of recursion steps.
