A few of us, here in Oz, have a pal who we call Pythagorus. No matter what it is, he always has an 'angle'. I wouldn't let him anywhere near one of my building projects though . . . if his life depended upon it, his maths wouldn't save him. Btw, I have just set-out my new raised garden bed. I had the idea of using the old mathematician's theorem and came here to reassure myself. It did. Tomorrow I dig out the footing to make the 10' timbers level. I can feel a few more beds coming on. 😃😃 Thank you from Oz. 🇦🇺
This was my go to method when I did metal roofing many years ago. The only time it doesn't work is when you have someone that can't build a building square. Using the 3-4-5 works great but it really shows how bad the roof is out of square when it's not built correctly. Great video!
Thank you so much, I've been trying to figure out how to make a 100x200ft rectangle with 90° angles and this video out of the 10 others I've watched is finally what made it click 😅 .
Just as you said it... I too was thinking that I owe my math teacher an apology. Thanks for explaining this and running through the concept. Greatly appreciated!
Great short video getting straight to the point all while keeping it simple and educational. I wish more TH-camrs would follow your lead instead of telling us about their day and what’s going on in the world and how many eggs does a chicken lay that morning before getting to the meat of the video? Thank you.
Thanks my frie;nd for this very helpful video. Now I'm sure I'll get my right angles right. And please , yeah...call your teacher and thank her , she'll be happy to know what she taught you is really helping all of us !!! Your friend from P.Rico, Edwin Oliveras
This is so true... I owe my teacher an apology too, but I had to use this method to line out the profile board of a new construction project after arriving on-site and realized I left my carpenters square back home.
If you want to create a right angle you have to come at it from the 3:5 line because only when you have the two lengths pegged will you be sure that you are getting a right angle with the last leg which will ONLY BE 4 if it makes a right angle triangle. If you do it the way in the video using the 3 & the 4 you have already constructed your right angle (which may be wrong or inaccurate) and will have too much or too little string along the hypotenuse. The Megalithic stone builders knew this because they carried around a circle of rope with 12 knots and constructed their right angle triangle accordingly. This is 5,000 years before Pythagoras called it his theorem. Examples of this can be seen at Carnac in France using the 3:4:5 ratio.
90 degrees Establish 1 straight line Make a circle with centre on the line Make another circle down a bit from first circle using same radius Draw a line through where the 2 circles intersect That is exactly 90 degrees
40 years ago I worked with a guy putting in fountains he swore by his book on squares and polynomials he would look up the hypotinous of each corner. This was very helpful laying out footings using a plumb bob with large changes in elevation
Another way is thus. The angel on the any points on the circle support by two points of it circle's diameter end points, is The right-angle.If pointer pole is fixed at center of other double lenghted pole and the pointer can move around, what positions would be The three edgs are formed always be The points are right angle forming. . So The tool also good one.
Any information on how to add building up. My job requires a drawing for every building including measurements. Just looking for other ways to add up large building. Closing them out with measurements that corelate to the shot distances. Typical match north to south and east to west to get equivalent measurements. I understand perimeter and how to add a straight line but there's another solution that involves adding and subtracting
This maybe a dumb question, but if you are off on the 3,4,5 measurement, how do you determine which point needs to be moved? for example, if you pivot the triangle on the tail end say 10 degrees, it would still measure 3,4,5 but not give you a straight line?
Does it matter which way you measure the 3ft and the 4ft dimensions ? For example where the lady measured 3 if I did 4 then 3 the other way would it basically be the same ? Just curious 🧐
Heyy same here, few days ago i really felt so bad, what was i doing when they were teaching me. Never took maths seriously, now i realise d importance of those formulas
I was talking to chatgtp yesterday about this. Pythagorean theorem sideAsquared+sideBsquared=side Csquared. With the correct size strings you could layout pyramids. 9+15=25. The square of 25 is 5. Im just celebrating understand it, and seeing it in practical use. Cool tutorial :)
@@Shepardofman Yes. To see what it could do. The conversation started someone where along the lines of 'teach me mathematics'- Then I requested information on something I had a hard time with in school. The phytagorean theorem. After I relearned it, I realized I could apply it to the solar shed/stands I was building. I was having a tough time squaring off the foundation. Full circle. Friend? No, you are my freind, oddly enough... ChatGTP is a toy and tool. A ridiculously amazing tool. Speaking of tools. :)
I’m no dummy, however... what is this used for exactly in the garden? I don’t know?? 🤷🏼♀️ this would be great to add to my knowledge base. Thank you ❌⭕️♥️
The 3-4-5 Method utilizes the Pythagorean Theorem, which is expressed as c² = a² + b². You can search for a 'Pythagorean Theorem calculator' online, enter the lengths you have, and it will calculate the length of the hypotenuse for you.
No, 3,4,5 are just coincidentally convenient numbers to remember. They work because of the formula - A²+B²=C² If side A = 3 and side B = 4, than: 3² = 9 (3x3) 4² = 16 (4x4) 9+16=25 √ 25=5 (25=5x5) If side A and B are both 4 than: 4² = 16 (side A) 4² = 16 (side B) 16+16=32 √ 32=5.657

The right way of explaining the Pythagoras on the sight. Excellent.
Thanks for this. Alot of us carpenter out there still need some guidance, everyday we learn something
Great and simple explanation ! Best i have seen so far.Thanks !

You are right.
Thank you, so much, for taking the time to post this!! Dang it, I should've listened in math class 😜
Good job. Do u have a good job for civil engineer. I have more than 15 years of work experience in building estimate and finishing work.
Me too..lol..didn't know this method before
Excelente explicación muchas gracias felicidades desde Panamá...
Oh! thankx a lot, it was so simple, I watched a lot of videos but failed to understand. Grateful to you, once again thankx.
Nice information and good explanation.
Thanks for sharing.
For bigger corners use 6-8-10 and so on. Been using this method for 30 years.
Personally, I like to use the 12-16-20😁
I'm sure the teacher is very happy that you're applying the P Theorem in real life. Thanks for this video.
good video thank you for explanations , and also you have a shining smile
You can also use the 3,4,5 method in surveying in-order to avoid obstacles when surveying ..that was when I realize Pythagoras theorem is helpful
90 degrees
Establish 1 straight line
Make a circle with centre on the line
Make another circle down a bit from first circle using same radius
Draw a line through where the 2 circles intersect
That is exactly 90 degrees
40 years ago I worked with a guy putting in fountains he swore by his book on squares and polynomials he would look up the hypotinous of each corner. This was very helpful laying out footings using a plumb bob with large changes in elevation
you can also use this for measuring building angles, seeing if a wall is square or if exterior walls are angled or not.
Wow simple and straight to the point, thank you

The angel on the any points on the circle support by two points of it circle's diameter end points, is The right-angle.If pointer pole is fixed at center of other double lenghted pole and the pointer can move around, what positions would be The three edgs are formed always be The points are right angle forming. .

So at what size would a structure be to large to use the 3-4-5 method?
But there's nothing about finding the right angled 3ft leg. Just "measure 3ft out and it should be 5ft from the 2nd pin."
What if it's not?
wow, this is very informative! Thanks you for the Video. 😍🤩
This maybe a dumb question, but if you are off on the 3,4,5 measurement, how do you determine which point needs to be moved? for example, if you pivot the triangle on the tail end say 10 degrees, it would still measure 3,4,5 but not give you a straight line?
Actually she is dumb. If we do as she says, we will never get a straight line right angle.
Was wondering this myself?
I'm not going to apologize to my maths teacher, but in going to thank my English teacher because I'm able to understand what your saying :)
Thanks for tuning in! Happy gardening!
Same to you
So does that mean I would have to do the same for my other corner ?
Your pegs should have a level on them to accurately make a true "right angle"..
So nice of you.thanks
Buena explicación, hasta y a persona que no habla inglés la entiende.
Felicidades para esta bella joven.
The best explanation ever
Does it matter which way you measure the 3ft and the 4ft dimensions ? For example where the lady measured 3 if I did 4 then 3 the other way would it basically be the same ? Just curious 🧐
It would be basically the same!
Great video! Thanks for posting! Mill Gap Farms
Wow nice method and idea
Thank you and I applaud your presentation.
Do we need to repeat this method for each corner?
great work dear queen
So you only do one corner? Or do you do all corners
Thank you for that method I helped more
Thank you so much, so much easier to understand.
Ah, Pythagorus. He dines in heaven now with the angles.
Stealing this 😂😂
For stealling from vedic math, mathematician Baudhayan
Good one 🤣
God’s* There were no angels in greek mythology
@@94ToBor Plenty of angles though. ;)
Mam how to lay out building with a deep excavation like 6mtrs below the ground
Would you do all 4 corners like tht?
If I have a 200 sft plot ,how many feet should the width be and how long the depth would be,
hi ,which biger number i can use ?i need moer then 6-8-10.i will be build 12mX5m
Such a beautiful explanation 👍👍👍
Awesome!! I was searching for the measurement ideas
Heyy same here, few days ago i really felt so bad, what was i doing when they were teaching me. Never took maths seriously, now i realise d importance of those formulas
This is something teachers an use to introduce a lesson on Pythagoras' Theorem.
Great video
thank you for u use easy and practical way of showing it
Very wonderful teacher

What if want to make the number larger than 3:4:5 ,how would be that,?
The 3-4-5 Method utilizes the Pythagorean Theorem, which is expressed as c² = a² + b². You can search for a 'Pythagorean Theorem calculator' online, enter the lengths you have, and it will calculate the length of the hypotenuse for you.
What if you want to make all sides the same? I mean instead of 3-4-5, would it be 4-4-6?
No, 3,4,5 are just coincidentally convenient numbers to remember. They work because of the formula - A²+B²=C²
If side A = 3 and side B = 4, than:
3² = 9 (3x3)
4² = 16 (4x4)
9+16=25
√ 25=5 (25=5x5)
If side A and B are both 4 than:
4² = 16 (side A)
4² = 16 (side B)
16+16=32
√ 32=5.657
oh to get the right corner is the first step but to adapt this right corner with respect to environment/surrounding view angle is the second madam
Sorry to all my teachers. I should have listened
Nice. I need to weld my steel doors to save tens of money. When things get out of budget then you have to learn to do by yourself and save money.
1million thankx for you...from Pakistan
Thankyou for charing🎉🎉❤❤
its a faster and finest method. i like that(3_3-5)
Thank you friend
How to measure whole building into square feet please show me
Any multiples of 3,4,5 work not just doubling
Very easy but not need all this thanks India
Hi, can someone help regarding how to make a symmetrical triangle building 10.3 meters by 6.2 meters thanks
Very Interested Method 3 4 5
Great video 👍
Actually it is a Pythagorean’theorem and you can use any three number that you want
Literally says this in the video, thanks though.
If you're wondering, for metric just use meters.
you can also X measure it too
Thank you for remember it for me.
Thank you so much for this video.
So helpful
