If I may respectfully interject here, I have found using the 345 method is really helpful but I Go with 3 feet, 4 feet, 5 feet. Not inches. I believe it gives a more accurate square
I always used a 2 foot framing square and string line , I guess how You get a square corner is really similar . If you had framing square against 2 pegs and pull string line in and out to establish right angle on the other leg of the square you can move the line in it out to line up with square and run a 100 foot line pretty damned square.Then take your diagonals measurements and I like your method to check and adjust corners. 3,4,5 inches, 3,4,5 feet ,6,8,10 . Good easy to understand explanation you did!
So I’m guessing you have a 40 foot square. This method works great. I used it in feet instead of inches. But you get the idea. Thanks for sharing. Some people are always going to have something stupid to say.

Why not use feet to get even more accurate? You can even do 6’ 8’ 10’ to get even more precise.
fantastic / thank you for showing this as very simple and effective
I’m gunna try it. I’m making 4x 4 M slab for shed. I hope it works.
Why am I hopeless at Maths?
A(squared) + B(squared) = C(squared)
thanks very much for uploading
For more accuracy you have to multiply these 3,4&5 with same number.
what if you are starting from a known point and need to make everything square to that?
Use a square lol
It's just better to use a tool called a square a lot faster.

90 degree angles don't change over distance.
String lines should extend and intersect, not run in a circumference..🤭
A+B=7???!
Ha aha ha
