I was taught this same method over 21 years ago, and all efforts to recall failed until I watched your video. Thank you very much for this very straight to the point video.
i do a lot of crafting and hate having to pay so much for so many templates. Your tutorials have saved me so much. Thank you so much for making this Grandmas budget. I have also referred your videos to other senior crafters. The guy who says it doesn't work is full of fecal matter.
For those wondering why it didn't work, it's because the construction is approximate: if |AB|=1, the radius |A5| = sqrt((4+sqrt(3))/8) ≈ 0.8465, instead of sqrt((5+sqrt(5))/10) ≈ 0.8507. Still, it means 0.5% precision, so it should definitely look OK, taking line thickness into account (as the video demonstrates).
Thx a lot I was struggling a lot in this subject and i am writing an exam in about 1 and a half hours. But i am now positive i am going to ace it all thx to you 😁
Ty very much i was having a hard time on my assignment draw a perfect same angle and side pentagon u really helped me❤❤❤i sub and like im really thankful i just need to watch a hexagon one and im good tysm again😊❤❤❤❤
A few years ago I searched for a method for construction of the regular pentagon which contained proof of its own veracity... I could not find one, so I came up with a new method which is impossible to forget. It starts with the Unit Circle, then finding the mid-point of the radius on the X-Axis, then add 1/2 of Root 5 to 1/2 and you get the Golden ratio on the X-Axis. Use your compass centered on the golden ratio point, and draw a circle with radius of golden ratio... Thus there will be 2 golden triangles drawn, one above the X-Axis, and one below it... The 3 points going through the Unit Circle are by definition 3 of the 5 points you need to make a regular pentagon, so just draw in the final two points. I should record a video of it, and post it on UA-cam. The base angles in an isosceles golden triangle are 72 degrees, which is 1/5th of 360 degrees...! 1/2 of root 5 is obtained by making the line-segment between points (1/2, 0) and (0, 1), then just use Pythagorean Theorem to confirm.
This looks very convincing, yet it turns out to be an approximation. If the base length AB is 1, then the height of point 5, h5 = (1+sqrt(3))/4; The angle we want is a= 2pi / 5. But in the drawing you think you should get tan(a/2) =2/(1+sqrt(3)); So a = 2 arctan[2/(1+sqrt(3))]; which gives a= 1.2638 However, 2pi/5 is 1.2566. It's only about 0.57 percent off. I got a little suspicious because this seemed such an easy construction. Too easy to be accurate 🙂 But pretty nice anyways.
At this point you will have to wait, as I am working on other videos at the moment. What I can recommend is to find the point used for a hexagon and just double the distance. That will give you the point for a dodecagon.
Well i guess i need to find a video explain the middle point method then come back when you placed the compass on 6 where is the compass set just random? Depend on the compass distance spot 5 could be out in space, ive Watched 3 different channels on how to draw a pentagon and every video theres a question i do appreciate you talking the other videos play music donr talk and just start slapping lines down and readjusting the compass and the title says SUPER EASY, probably is once you learn how
circumference of 18.22m divided into 30pcs arc, i want to draw one of the arc with 1.45m radius instead of 2.9m radius. pls assist me i have sent message to you on messager facebook too

This is the first time I've drawn a perfect pentagon. This method is spot on. Thank you ❤
nothing is perfect
no one is perfect
jk, just a joke, well done bro😁
This is not a perfect pentagon. perfect pentagon can not be constructed using compass-ruler
I have been struggling to construct pentagon but now found it easy after watching this video❤

Bro wtf
Wow thats fantastic
So if we draw a big enough pentagon with a small enough nib would the defects show?
@@Someone-qd8up Yes, definitely - that's what the above numbers show.
Thanks for keeping me sane, I was following along in AutoCAD and the error definitely shows up 😅
Thank you so much for this video!! None of the others I tried were exact. Yours was PERFECT the FIRST TIME!!!
Glad I could help.
THANK YOU! This been causing me many sleepless nights xxxx
Your methods is very good, easy and accurate. Thank you so much
You're welcome.
It really helped me in my school project ,thanks please keep it up by making more
You're the best...I thought I could never do TD but you made it easy👏👏
You the best wrote a EGD grade 10 test and you helpt me 🎉
Glad to help. Hope the test went well.
Thank u so muchh u helped me ace my exam god bless u!😊😊
I was looking for this method for hours ... finally found it ...thank you for the detailed explanation 👍🤗
You're welcome, although I still recommend method 1 on this channel because of accuracy.
Good
Hey😂
I really understood, thank you so much 😊
Thanks. Just the method I was looking for.
Good to know, hope it helped
Love from Bangladesh 🇧🇩🇧🇩🇧🇩
This video is really helpful...
Thank you very much
You're welcome
Ata ki regular pentagon??
Thanks to you i can pass my Basic Technology tests.
Thx a lot
I was struggling a lot in this subject and i am writing an exam in about 1 and a half hours. But i am now positive i am going to ace it all thx to you 😁
You're welcome, and glad it helped.
@@Wimmas it did a lot thx and i got 100% on the exam thx to you 🙏
It was amazing ....I think this is the easiest way to draw a pentagon......👌👌
Ty very much i was having a hard time on my assignment draw a perfect same angle and side pentagon u really helped me❤❤❤i sub and like im really thankful i just need to watch a hexagon one and im good tysm again😊❤❤❤❤
great content.
you have a new subscriber.
i learnt something.
Thank you
Thanks your videos are very useful and your methods are simple
So you dont need the mid point lines below the A B line?
Very helpful thanks the instructions were awesome 💯
Thanks
This is the best vid ive seen wow it was really helpful
I Am Indian I Am Very Happy 😊 For Your Teaching Way
That's great to hear.
Thank you its great short cut pentagon..
Thanks a lof for shareing your technic
You're welcome
Thank you for teaching me how to draw a pentagon
Thank you so much, You are a lifesaver
Glad to help
It was helpful last year
Thank you this year
Very helpful, thank you. The top of my pentagon did not meet the top of the circle, but all sides were equal.
Thank you sir it helped me alot
Thank you very much, this helps me really well. Keep it uppp😊
Thank you for your kind words.
Very helpful 🙌🙌
Very useful video thank you sir
You are really doing a good job
Thank you😊 very much I am understanding very well 😇and you doing good videos and all the best 👌
You're welcome, and thank you for your kind words.
Sir,
I tried thrice but there is a problem in the second last step while intersecting .
Then try method 1 on this channel. Its a bit more accurate if you struggle with the second last step
Thanks I get more from this technical drawing
You have taught way more in one video that my art teacher in her whole career
bro math teacher not a art teacher bec its a PENTAGON
@@_GhostGamerYT_wtf?
I am sorry to hear that, and thanks btw.
Finally done!!! Thank you..
You're welcome
Is anyone watching this just because of exame 😂
Me here 😂😂😂
Current situation 😂😂😂
thanks for your tutorial sir.
You're welcome
Anyone in 2024
Thank u so much
This is very useful to mee...
U Made this so simple thanks 👍
I'm so good at this thank you 😮😮
Thx a lot I was really helpful this for make a dodegahedron
This is very helpful thanks for I have passed my waec

Liked the neat method, but it would have been nice to know the logic behind this method.
this is really nice😊😊📝
Thank you
Bro what was the length of the first lines wth a and b bro
Thank you❤
What is the distance of line AB
Thank you and i know how to do my math homework 😅
Thank you very much🎉🎉🎉❤❤❤❤
very nice , thanks a lot
Anyone having exam?
SHUT UPP
Yes
Literally me rn
Thank u soo much ❤
Is it a regular pentagon??
Correct
Anyone revising a night before exam
Can u do nonagon and heptagon
Best ❣️
This looks very convincing, yet it turns out to be an approximation. If the base length AB is 1, then the height of point 5, h5 = (1+sqrt(3))/4;
The angle we want is a= 2pi / 5. But in the drawing you think you should get tan(a/2) =2/(1+sqrt(3)); So a = 2 arctan[2/(1+sqrt(3))]; which gives a= 1.2638
However, 2pi/5 is 1.2566. It's only about 0.57 percent off.
I got a little suspicious because this seemed such an easy construction. Too easy to be accurate 🙂 But pretty nice anyways.
Well done.
thank you for the pentagon ,, can i have one for heptagon
Working on it.
I'm here for the Golden Ratio.
Pls can you do a video of a triangle and oval
THANK YOU SO MUCH
Please do a video how make a dodecahedron
At this point you will have to wait, as I am working on other videos at the moment. What I can recommend is to find the point used for a hexagon and just double the distance. That will give you the point for a dodecagon.
Can this be done in grade 7
Thank you!
