My favourite ways to divide a circle into however many segments you want using a compass and straight edge. Perfect for making mandala grids or any number of DIY projects really.
7, 9 and 11 aren't 100% accurate but they're extremely close.

You should be twirling your pencil as you draw to keep the tip sharp. It results in consistent line width/weight, and less sharpening.
Likely the most informative video on the subject. Thank you
I first watched your videos after Lou Davis recommended your instructions on geometric art. Honestly I was mesmerized, how DID you do that? And in the past few months I have watched and rewatched videos and have learned to handle a compass (watch out for the point!). I am beginning to create a few simple designs and having fun. I love the combination of lines and color and use these designs in my modest watercolor paintings. Thank you for these videos, and your time and your expertise. We all need challenges, and successes, those AHA! moments. Thank you for letting me have some.
Brilliant thank you ❤
me encanta, la precisión es absoluta.
para pasar de 3 a 6 y de 5 a 10 con prolongar las lineas hubiese sido suficiente.
bravo por el canal, cada día me gusta más tu trabajo😊
👊👊👊
3:39 BRAVO!
Merci, court efficace pratique et basique ! Soyez béni
Thanks so much for your amazing videos!
thanks mate! i could not figure out how to divide it into 5 sections!
Теперь я знаю как поровну разделить праздничный торт, в какой бы компании я не оказался, Спасибо! =)
Thanks man. As a geometry enthusiast, I have to know this stuff. I will practice this over and over again.
9- уголльник - больше спасибо! Очень полезная информация! Способы, которыми я раньше пользовался были или слишком сложные в реализации, или не достаточно надёжные
Geometry made
Me understand division more now than it ever did before, knowing odd numbers and how they can be divided really made me look at Platonic solids in a different way, 9 and 12th star really interests me, when before all I drew was hexagons and cubes
❤️✨ no coincidence ... Thanks again! 🙂
That 9 💥 is cool af bro 😎, this will be watched a few times I can tell ya thanks for your support and help so much appreciation for your work ❤🌘
5, 9, and 11. Wow!
Great info!
Man ive been contemplating how to do the 9 for a few days so as to study the enneagram then wham! There you are... with all these extras too. Cheers dude. Cheers universe. Great channel man
super vidéo et bien claire pour diviser un cercle en plein de morceaux
Жаль ,что можно только один лайк !!!супер ,ты чувак очень крут!!! Спасибо за вдохновение!!!
Maintenant y'as 15 👍👍👍💎
I found this ...
It’s impossible to construct the angle 2π9=40∘ using a straightedge and compass. (It is possible using a marked straightedge or a ruler)
The problem comes down to trisecting angles. We can trisect our circle once, giving 120∘=2π/3.
Bisecting is always available so we get π/3 and π/6. But there’s no way to get 2π/9 without another trisection, which is impossible with a straightedge and compass.
Very useful video, thank you 👍
😲 Doesn't anyone remember this being taught in mathematics class in school!
😲 Thanks for refreshing my memories of deviding circles!
😲 It's been many decades and I don't think the school systems are doing good for our future generations! 🙄
Merci 👍💎

Красота !!!
👍👍👍👍
Thanks , hopefully my coils will produce .
Thank you, thank you, thank you and thank you 😅
This is perfect for those to understand the symmetry of each number, and to understand not each number is whole 👍📐
Sublime
nice
Intriguing. Have you worked out the proofs or are your results visual? Nice work and thinking. Would be interesting to see what you kight come up with using teh 7, 9, 11 divisions.
Definitely just visual, these are mainly to be used with artwork.
Proof? Like 360÷9=40°? Or 360÷2=180°= a straight line through the center?
I know it's definitely not 'sacred', but can you draw the biological hazard symbol? It's got interesting geometry
I'm always off when i try to divide into 5.
Ok, so divide by 10. Then divide each of those sections by 4 by halfing them twice. That should be 40 equal sections, right? Gonna try soon just doing some research
Great
It would have been great if you had made it to number 12 at least. You know, it's a semiperfect, highly abundant and superior highly composite number because of its factors (2, 3, 4 and 6 excluding 1 and 12 itself).
Just cut the 6 in half
Cool
🤩👏👏👏👏
Do you find that your pieces have an energy foot print?
Not the creator of the Video: But for me they definitely have. I'll have to take a break from time to time because i feel somewhat overwhelmed when drawing.
hi i am new to geometry, and i am practising with my compass but i keep making holes in my paper XD Is there a way to prevent that?

How to divide circle into 45 equal parts without protractor?
5.. isnt ready you have to Draw 10 more circles than its Fits perfectly.. 🙃
🤓👍
Yay I was wondering how to do this 🐒
Now you know mi amor ❤️
👍
pretty nice, however, I think your way for dividing into 9 is overcomplicated. It could be much easier, for detailed instructions, see the tutorials on Arthur Geometry channel.
Who said math is easy 💀 like how did they even discover these bruh btw thanks
Practice. #Mathematics 🤔🍷☕
Nice you ended on the 11, just keeps repeating after 12, no pun intended, so does clock, goes back to 1, this should be taught to children so they can understand the times table more
Clearly
I do not think dividing the circle into 5 equal parts is done accurately. Mathematically speaking, when you found the 1/5th of the diameter, it was not accurately divided into 5.
Not true at all, that’s a very classic pentagon construction.
Though the heptagon and nonagon can’t be constructed with only classic compass/straightedge (unless he’s using some more powerful technique like neusis), but it looks like just a good approximation.
The 7 didn't work either.
Are you claiming to have divided a circle into 9 EQUAL parts? I ask, because it would mean that you have constructed a 40 degree angle, which is known to be impossible. If you are claiming to divide the circle into equal parts, please provide a proof for each of your constructions.
Na I'm not claiming that, it's just for mandalas and geometric art
TLAZOKAMATLI!!!
