Polygons are frequently referred to have particular names. Some of these are listed below.
A pentagon is a plane figure bounded by five sides.
A hexagon is a plane figure bounded by six sides.
A heptagon is a plane figure bounded by seven sides.
An octagon is plane figure bounded by eight sides.
A nonagon is a plane figure bounded by nine sides.
A decagon is a plane figure bounded by ten sides.

WTG, @2:09, YOUR SPONSOR POPS UP AND BLOCKS THE WORK IN PROGRESS !!
Yes ,you are absolutely aright
thx u 🥺❤️ heh.. I'm done on my assignment 😭❤️🤭✨
For anyone thats interested: Music: Tarazanio - Jazziano
Fast easy 👍
I am about to make a fidget toy in the shape of a pentagon. This video really helped me. Thanks
good video
Thank you .I finally can finish my maths activity
I think we can make it in a very easy way
But this method helps to learn a lot if we understand each step
Thanks a lot 🙏
Thanks mate, it uses the flower of life also
Well explained. Easy to follow. Keep it up!
Thank you sir! by the way what's the name of music in the video : ]
Jazziano
Awesome method
Thank you, very helpful))
What about dividing into portion
nice background music
Very helpful
I've done a construction with compass/ruler of a regular pentagon/pentagram. This one seems simpler. I'll give it a try.
Golden rule number .5*(1+sqrt(5)) helps. Half of that is sin(54 deg).
Very easy n nice
Tq sir
Good method
👍👍

FYI, you are using dividers which are only good for measuring.
A compass , which has a geared wheel in the center, should be used for drawing circles since it is much more accurate.
Seriously what the heck🤔
You musn't say that to hurt him or her
@@joelsanni1696 Musn't say what? I was just pointing out the differences between the tool being used, and that there's a better option. (35+ years as a professional draftsman)

Ye song to hotstar ke ad me aata hai😂😂😂
Set the dividers at 50 m.m. and then show 60 m.m. The finish product showed some error on the last point of construction,
Yo any body else vibe to the playboi carti in the backround of this mans video
Good
The drawing are very invisible I don't understand
Wow i has very invisible
nice music
Kya bhai etni der me Pentagon bnaya toh time hi nikel gayega
Porque no lo hablan para que sea más claro
Sangat mendidik
Selamat datang😊
Tried it longer than 50mm so many times and it's just not accurate :((
But the 50mm worked.
Funny you sound say this. I tried something of this scale initially, and it worked out. I figured larger would be better, as there would be fewer "rounding errors", but I've encountered the same issue as you. This doesn't scale up. Which means there is "flaw" which is hidden with a 50mm circle, but is revealed with a larger circle, or something else is wrong. Notice at the end of this video the 5th line segment doesn't "exactly" line up with the starting point. That could be an indication this method doesn't yield a perfect 72 degree angle. I've never seen a technical description of why this construction works. It could be this is close to a pentagon, but not exact. This is still better than free-hand drawing a pentagon. :)
Oo
Very hard method
It can be shown that it does work using geometry, algebra, and law of cosines. It is not an approximate method. Errors in construction are of course possible.
The last step, marking off the circle with the points, is the source of error.
Stepping around the circle in one direction will introduce an error, as seen.
The length used in stepping is a tiny bit off, so the marks are slanted in that direction.
Step around the circle, using the same starting point each time, but a clock-wise pass and an anti-clockwise pass.
Each point on the circle now has two 'steps', instead of one.
Clock-wise steps drift one way, anti-clockwise steps drift the opposite way, at the same rate.
The intersections of the step-marks is the correct central angle for the pentagon.
Draw a line from the center of the circle through the step intersection, and where that line crosses the circle, make your dot.
Connect the dots, Pentagon!
pero porque en ingle???????
Hands are in the way too much. Might as well blur it all.
That literally made 0 sense and i thought as a grade 7 student, I’d be able to understand
Your school probably uses a different method or you're just dumb
very tough method , very light lines please use dark pencils😕
Yeah
Very hard method
I didn't understand this method
I love your videos I am just trying not to hurt your feeling I hate them like seriously what the ****is this just kidding it helps and 13kkj or y stop saying nonsense
4-semester ka isometrik project chahia
Happy sale
Way too fast to follow!! Slow down!!
Pause button.
You're wrong
Hi
try in other simple method its easier
Wrong...🙏
are hmare samagh m nhi avay bhai
Very Hard method
Akash
Sorry this was a bit too fast and complicated..
omg,,sorry for inconvenience..
Why do you have to make drawing a pentagon so fucking complicated there are better ways than this that don't involve re aligning the planets..
urcopy writing make ur own better.
Haha so black hand
thanks.....hee heee heee......
Racist
RACIST I:( not cool
RAJESH shrestha
Color does not matter
His color can be black but he is smarter than you
See his efforts that he is making to make us understand
Wtf? Does some actually not know how to do this? I thought this was thought at school as kid.
Bad
Good
Good music too
Hi
