[edit] something wrong?
ive tried the construction method shown and everytime i seem to be way off. im just not getting 10 = points. —Preceding unsigned comment added by 71.232.147.54 (talk) 21:22, 4 April 2011 (UTC)
- The construction is a bit tricky. Possibly you are not setting the correct radius at some point. Does the alternative method work OK for you? Dbfirs 09:29, 5 April 2011 (UTC)
- the alt versions using the pentagons also seem to be a bit off. I know i can do it with a protracter, but there is a satisfaction to doing it with just a compass and straight edge, however I just can't seem to get any prescision. The final measure always seems to be off by a few degrees. my only guess is the measure must be very intolerant requiring perfect pin point measures with even the thickness of a pencil throwing me off or there is a flaw in determining the final radius wich determine the chord lengths. has anyone else actualy tried to draw these with pen and paper?

- I have gotten some very good and accurate results with Regular pentagon#Carlyle circles method that doesnt have the closer errors of the others seem to leave when i try to draft them. Bloodkith (talk)
