Notes: Sometimes the string can introduce some errors because of its flexibility. Therefore, it's always a good idea to recheck the 3-4-5 after your lines are snapped. In addition to multiplying the ratio, you can also divide the numbers to get even smaller numbers.

How come the 2nd time your starting point is the same point but the first time your starting point is the outer edge on each side that is different length (4 and 3)? Doesn't that introduce an error in the diagonal?

Mathematician here. Nice mathematical video :-) It's actually not the Pythagorean Theorem that is used in the 3-4-5 method. (I don't think the video claims this, but some comments do.) Instead, it is the converse of the Pythagorean Theorem, which says: IF the sides (a, b, c) of a triangle satisfy the equation a^2+b^2=c^2, THEN the angle opposite side c is a right angle. In the 3-4-5 method, this is used for a=3, b=4, c=5. For the same reason, there is also a 5-12-13 method. (And infinitely many other similar methods that are not just scaled versions of these to methods.) Another funny thing I have noticed: Almost all woodworkers on KZbin say "square" when they mean right angle (when two lines are perpendicular/orthogonal) :-)

Guys just start out with a any number that is a multiple of 3. Then however many times 3 goes into that number, multiply 4 and 5 by that same number. At the end, the measurement between the 3 side and the 4 side should equal 5 times whatever the number was you used to multiply with. If you start with 3x4=12. Then multiply the 4 and 5 by 4 also. 16 and then you would get 20 between the first two. It's really really simple if you know the multiplication table.

We use a chalk like to transfer a line to a concrete slab, sub floor or any other type of substrate in order to follow. We use this line to keep all the material straight and square, it is very important to follow. If you don’t follow your line correctly, you can have a huge mess on your hands and its a nightmare to fix if you don’t "catch it" right away.

very cool. it got me thinkning.. situations that are square but not 3-4-5 or a simple multiple like 6-8-10, Is it true that every square 3 sided measurement is a derivative or multiple of 3-4-5? Kind of like if a truw box is really square, divided by itself is 1. So every truly square triangle measurement would have to be equally proportionate to 3-4-5...? never thought this deep before lol

@TrainingHandsAcademy3 жыл бұрын
Fantastic question Gary! Just as you can multiply to make the ratio bigger, you can divide to make it smaller. So for your project one option would be to divide the 3'-4'-5' by 2 to get 1.5'-2'-2.5'. Cool right?!
@emirkanaa3 жыл бұрын

@Tommy_0072 жыл бұрын
If you prefer integers that are as large as possible (and still inches), then you can multiply by an integer n so that 3*n is at most 24, and 4*n is at most 48, i.e., you multiply by n=8: 3 becomes 3*8=24, 4 becomes 4*8=32, 5 becomes 5*8=40. Therefore, you now have a 24-32-40 method.
@richardslater6772 жыл бұрын
It’s a ratio. It doesn’t matter what the measurements are as long as they are 3-4-5. You could use 24 on the short side, 32 on the second side and 40 on the hypotenuse. 24-32-40 is the same as 3-4-5. Better still, forget it altogether and just measure the diagonals.

Don't worry about unit of measure. It can be something you invent. What matters is the 3,4,5 all being multiplied by the same number each time. It's much easier to understand with the short simple explanation. The longer it takes to explain this the more confusing it will get.

You don't have to go 3',4',5'. Use multiples of 3 if that works better. Say you use 12. 3x4=12. Now multiply 4 x 4 up the other side. That's 16". Now if you measure between them you should get 20 because 5x4=20. I just used 12, which is 3x4. Then I multiplied the next two numbers also by 4. You can do it however works best for the project. Just start with any number that is a multiple of 3.
