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.
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!
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.
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.
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.
It may or may not be an accurate construction for 5, 15,17 and the other known constructible polygons (31 in all) with an odd number of sides, but 7, 9, 11, 13 etc are known to be impossible with only a compass and a straight edge. These are, at best, an approximation.
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...
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...
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.
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.
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?
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.
Use the compass set to a bit more than half by eye, then draw arcs from each end both sides of the line. Join them they cross the line at mid point. Tip. Use sharp compass and pencil
Thank Yiu For Highlighting The Important Issues So Beautifully..💞💞
Good drawing
I LOVE IT ❤️ 😍 💖 ❣️
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
Same broo😅
Which uni u are studying
WOW! That is SO useful: THANK YOU!!! And so beautifully presented - very clear.
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 😢
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!
Great illustrations👌and of course it doesn't hurt that it has satisfying sound effects 😄
Exactly
Super teaching sir good i understand you telling is very easy nice
Thank You ! This is the basics of Quad Step Helical Order.
Thank you very much for great explanation sir🎉🎉
Very nice after before 40 years ago. I did . thanks sir.
Thanks very much for this great information sir, very clear demonstrations and easy to follow. Great job ❤❤❤❤❤
I love it make me understand thank you very much.

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 RUclips for detailed and clear explanation
You will learn in 7th or 8th grade to draw side bisector and angle bisector.
You will be the reason I pass thank you soo much 🤧🤧
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
This explanation and illustration was extremely helpful, now i can easily construct any angle of polygons.
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.
could you please let me know what is the basic theory behind it
Wow nice👍
Excellent tutorial. Thanks
Must be used in analytic geometry as well.

Excellent explanation😊
so satisfying 😊😊😊😊

Wait.....
This is EXACTLY what i needed THANK YOU SO MUCH BRO
Is that accurate at every ENDPOINT of the arc in the CIRCLE?
Lies again? Navy Seals National Service
Thank you for video ❤❤
Am going to try it cause it cause in class I failed to understand it but now I do thanks for clear explanation
Please, what software did you use...?
Anna big fan😘
Commendable animation
I love your method . Thanks.
No need to make irregular wiggly wiggly figures anymore😂😂. You become an expert in class.
which software are you using
Thank you
Thank u so much 🥰❤️❤️👏👏👏👏😌
You're welcome...
Very Thankful to 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).
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...
❤
So helpful in the work I do!
Amazing video, bro can you tell the name of this software?
me too im dying for it
Thank you very much
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!
It's understandable
😊😊
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
Satisfactory
thanks

😊
Very easy and good thanks so much
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 very much for highlighting
great quality
Its very helpful men thanks
❤
Nice one
Same with decagon, hendecagon, dodecagon, etc even icosagon.
Tq i have no idea after i see video some more clarity
Thank you very much
Is these all polygons are regular polygons?
Yes
Yes they are regular polygons
Very nice method

vraiment bravo pour tout, mais le triangle équilatéral c'est aussi une polygone régulier
Great
Wow
Thanks I'm really struggling
,💯💯💯
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.
speed up the process of drawing pentagon lines after you have already shown how you did with square, because its gonna get repetitive really quickly!
this was very hard and and this was not what i looked for
How do we get the middle point??
Use the compass set to a bit more than half by eye, then draw arcs from each end both sides of the line. Join them they cross the line at mid point. Tip. Use sharp compass and pencil
Pollichu annna cllas
Thanks man
I always look for the measurements
Mr sir. This method is not giving equal sides of all polygons. Nonagon in particular
It's just an shortcut method
As the number of sides increases it gives approximate values
it cannot happen in actual life
I checked
why it do be lookin like fibonacci
