Even if you have needle point accuracy, the polygons will not have equal length sides (except for the square and hexagon). You'll notice the video never claims the method will create *regular* polygons, but the diagrams show polygons that appear regular.
Recreated this in desmos geometry. It should be noted that the pentagon & heptagon aren't exactly regular, but they are very close to perfect, especially considering the fact that an actual heptagon has been proven to be impossible to construct with a pen & compass. though octagon & nonagon though are very bad & this video is blatantly lying. If you follow the method exactly in this video for the 9-gon, one side will be noticeably longer & angle variation will be more than 4 degrees for each corner. If this video mentioned that some of the construction are just good approximations then I wouldn't be leaving a dislike on this video.
This is an easy method for drawing polygons that are not-quite-regular. The sides are not the same length for polygons other than the square and hexagon, but they are close. Drawing a perfect regular heptagon with only compass and straightedge is impossible; with this method you can draw one that is nearly perfect!
At the 1:15 minute mark, there's no length given for how wide/short to make the compass, because of this there is no way to go further past this point in the video. Please correct this because I have tried so many lengths, short & long, and NOTHING has worked. Please correct this missed part, thank you.
I checked it out with trigonometric fórmulas, this method is not accurate. Apothema should be Side of the polygon L/tan(pi/n) where n>2 is the number of sides. This method leads to Apothema = (l/")+(n-4)*(l/4)(sqroot(3)-1), and they are not the same.
How to think about everyday things like studying so that I am right always and do the right things...?do like that because if you aren't organised, you are doomed...
You just earned yourself a brand new student (that's me) you're simply amazing, I love the fact that you include drawing instruments in your illustrations, makes my learning a step easier.
i tried more than 20 times in various platform either use ipad, openboard, real compass. and it only happen 1 time to get the regular for all types of polygon. the rest, all hv a balance after last side. can anyone help to explain whats wrong with me?
1. It's points A and B. 2. When we want to divide any line into two equal parts we use the middle point method, in which we take a compass and adjust it to a length which will be equal to more than half of the line which we want to divide...
The cheating required to make the heptagon aside, this is so elegant, quick and easy, quite impressive. I might suggest drawing all the polygons, including the square, with a vertex at the top. It makes a prettier finished picture.
I got it. First, there is no 'd' (as in the CC) {so ignore that}; second, 'take some length' really means take a length that is greater than half and less that a-b --then everything falls into place after that.
Thank Yiu For Highlighting The Important Issues So Beautifully..💞💞
Good drawing
I LOVE IT ❤️ 😍 💖 ❣️
It's not as easy as it looks here .. believe me ... a person has to be needle point accurate for all of these polygons to work out precisely .....
Even if you have needle point accuracy, the polygons will not have equal length sides (except for the square and hexagon). You'll notice the video never claims the method will create *regular* polygons, but the diagrams show polygons that appear regular.
I tried this again, and no matter how accurate a person is, it doesn't work, and I payed particular attention to accuracy........
At maximum accuracy I can do correct till pentagon. After hexagon it becomes irregular and error in circumscribing circle.
I got pinpoint aim
True bro 😢
Very easy and good thanks so much
No need to make irregular wiggly wiggly figures anymore😂😂. You become an expert in class.
Great illustrations👌and of course it doesn't hurt that it has satisfying sound effects 😄
Exactly
I found it very difficult when my faculty explained to me but after listening to your class, it's like heaven
Thank you for the class

But sir, when we are drawing the last side is not matching with the point 'A'
yes this is happened to me too. pentagon shape is not close at last point
Thanks very much for this great information sir, very clear demonstrations and easy to follow. Great job ❤❤❤❤❤

could you please let me know what is the basic theory behind it

Take the length more than half of the line you drew for the square
Like if you take 5 cm for the first line then take more than 2.5 cm.
It is called 'side bisector'. Search on UA-cam for detailed and clear explanation
You will learn in 7th or 8th grade to draw side bisector and angle bisector.
I checked it out with trigonometric fórmulas, this method is not accurate. Apothema should be Side of the polygon L/tan(pi/n) where n>2 is the number of sides. This method leads to Apothema = (l/")+(n-4)*(l/4)(sqroot(3)-1), and they are not the same.
Must be used in analytic geometry as well.
Here because I have exams later in the day 😂

❤
it cannot happen in actual life
I checked
Is that accurate at every ENDPOINT of the arc in the CIRCLE?
Lies again? Navy Seals National Service
You will be the reason I pass thank you soo much 🤧🤧
Thank You ! This is the basics of Quad Step Helical Order.
Amazing video, bro can you tell the name of this software?
I love it make me understand thank you very much.

WOW! That is SO useful: THANK YOU!!! And so beautifully presented - very clear.
THANK YOU
Can this method be used if question is given draw a regular pentagon 😢
No, this method does not create regular polygons (except the square and hexagon).
Thank you very much for great explanation sir🎉🎉

Super teaching sir good i understand you telling is very easy nice
Satisfactory
Very nice after before 40 years ago. I did . thanks sir.
A to B is not the same for each polygon. Each polygon has different chords, the dimension from A to B is a chord.
Thank you so much for this. Please, what software are you using...?
Mga inhs:
Excellent tutorial. Thanks
Excellent explanation😊
Am going to try it cause it cause in class I failed to understand it but now I do thanks for clear explanation
This explanation and illustration was extremely helpful, now i can easily construct any angle of polygons.
Thnx sir so much
You're welcome, If you find my videos helpful, I would greatly appreciate it if you could share them with anyone you know who may benefit from them.
Sir I like your videos
Tq i have no idea after i see video some more clarity
Is these all polygons are regular polygons?
Yes
❤
😊
Time points 1:00 to 1:14 makes no sense: 1) there is no point 'd'; 2) 'take some length' -what length? Thank you.
1. It's points A and B.
2. When we want to divide any line into two equal parts we use the middle point method, in which we take a compass and adjust it to a length which will be equal to more than half of the line which we want to divide...
@@ADTWstudy Thank you. I figured it out, I was confused by some of the explanations. Your method is very elegant!

Thanks I'm really struggling
Please, what software did you use...?
I always look for the measurements
So helpful in the work I do!
Its very helpful men thanks
Very Thankful to you😢❤
Same with decagon, hendecagon, dodecagon, etc even icosagon.
Thank you very much
which software are you using
What grade do they learn this in pls respond back
I learned this in 8th grade. SCERT text part 1 chapter name - polygons
@@m_x_sterious thank! Kool vides
Thank you so much sir
It's understandable
😊😊
Thank you very much
why it do be lookin like fibonacci
I love your method . Thanks.
Thank you for video ❤❤
great quality
Thank you very much for highlighting

Waoooooooh

Thanks man
Great
Very nice method
Tnq so much
Hi
,💯💯💯
vraiment bravo pour tout, mais le triangle équilatéral c'est aussi une polygone régulier
