3-4-5 Method

Took too long

Hello but what about in meters we don’t measure in feet in our country

this woman has nice pins.

THAT IS EFKLIDIS THEORY....

Good bro I’m carpenter from hong kong

you can also X measure it too

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.

Practical

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

Ridiculous

I owe Math's teachers apology, too

All these videos with women these days. 🙄

Very educative and beyond it all, the smile is great. Thank you.

Your pegs should have a level on them to accurately make a true "right angle"..

Thank you so much, so much easier to understand.

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 :)

❤❤❤❤❤

Great host. Well shot. Easy to understand.

Why you do not sleep in class….

superb

great work dear queen

Do we need to repeat this method for each corner?

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?

did you know the ancient Egyptians used this method 4,000 years ago?

That helps literally no one

Thank you so much ❤

Not helpful as you were already working of a frame in the ground which had a 90 degree corner. Duh.

theoreme de pythagore

So what do they call it in other countries
The US got the most catchy one 😂

Well xplianed😇💫

its a faster and finest method. i like that(3_3-5)

Great video! Thanks for posting! Mill Gap Farms

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 🧐

Great

Mam how to lay out building with a deep excavation like 6mtrs below the ground

What if you want to make all sides the same? I mean instead of 3-4-5, would it be 4-4-6?

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 ❌⭕️♥️

Thanks..

👌👌👌👌👌

Thank you so much

For big projects you can also do 6 8 10

the problem with the school system is that they teach u the equation but not how to apply it in real life..

V nice

That's cool. 👍

Straight to the point and so easy to understand.

At one point, didn't we all think we would never use most things we learned in school ? lol... And now... we know how wrong we were.

Good
