Draw a perfect circle with 5 points.
Anyone?

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?

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

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.

Calculators are forbidden

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...

How do you calculate the angle without a calculator?

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