Here is how I got my 5 points circle:
I created a star, erased the inside points, selected the 5 remaining points and adjusted the curvature until get a circle. To be sure, I compared it with a 4 points circle.

I won? I won?

Yup :)
what about a 6 points circle?
AFAIK the star tool doesn't allow select the number of points (which is totally silly btw)

I was writing this other answer before read about your new challenge :wink:
you can use bones as reference to get circles with more or less points.
for example, for a 3 points circle I created 3 bones of the same size with the same origin place. Then rotated each bone on 0 degrees, 120 degrees and 240 degrees (which means 360/3, a complete circle divided on 3).
Then I use that bones as a reference to add the 3 points. Once the points are on place, it's all find the right curvature.

PD: of course, using Fazek's polygon tool you would avoid all this steps.

Guess you don't have bones and don't have Fazek's tools installed.

LOL, I was doing it old school way. I took 360/5 to get 72 degrees and used tan18=x/1 to get the y point and sin36=x/1 to find midpoints of each edge so i knew when i used curvature tool i was at a perfect circle when i hit the midpoints. I guess I made it harder than needed to be. Anyways it made me unfreeze the trig side of my brain that's been dormant for years.
Sorry for bad animation

When you finish the 6 points circle, please go on with the 7 points one. It is possible ;)

hehe, I have 3, 6 and 8 point circles. but can't get the 7 points one!
It's so hard!
I'm trying to think as Genete does... let's see, If I would created the spring mechanism...

could 7 be hard because its the only number between 1-10 that cant be divided into 360 even?

Ok, you can rotate a line by angles too, so you can use lines as references. But I'm sure it's not what Genete is thinking about.

Here it is:

I did not use the calculator to place the points.

I just did this challenge to pray for the addition of a Star tool with options... :( :roll:

How do you calculate the angle without a calculator?

I said it, I'm thinking as Genete does, my brain is very fast :roll:
