I figured the Pythagoreans were a group of people from a region, like Pythagorea. See Sparta-Spartans, Athens-Athenians, etc.

So I asked the guy what he knew about it, if it was one man, a region, etc. and he said it was a region and specifically probably one person, but they had built a whole religion around the use of the numbers.

I'm not sure there wouldn't be some connection to the free masons. Once you master this knowledge, it would be very powerful. Just think of the respect given to someone today who can master all the information on a framing square.
The framing square is a piece of cake, now the Chappell square- that's got some info on it!

The long side of a right triangle is the hypotenuse. The shorter sides commonly referred to as the legs.

I'm still working on perfectly square cuts on larger stock using a japan saw. It really is a zen thing. However, zen don't pay!

3, 6, 9! See, Paulie? You're just too young.
I think it's growing up doing songs that kept you thinking that makes us wonder what has happened to that ability in so much of the younger generation.

Here's another one of hers.

Yeah, his name was Pythagoras. He was a mathmatician and philosopher. And no, not related to the free masons. They wouldn't come along for about another 2,100 years.

It's a good thing somebody invented a chalk box.
When laying out walls 6 8 10 is usually used but I have found that when I'm working by myself I would rather snap a line and pull equal meaurements from my point of origin in opposite directions and then draw intersecting archs and snap through. It just seems easier when working by your self. And on sites where there's allot of crap in the way such as gang boxes the pls5 works great

Re: 3-4-5 Squaring Method


also known as Pythagorean triple's, the 3/4/5 is joined by the 5/12/13 and a few other combinations whose numbers are whole. The 3/4/5 is great when laying out a pole barn to create perpendicular walls (as in 12/16/20).

I know its the Pythagrorean therom but I learned it as the 6 8 10 way to square up two perpendicular lines. Also that there are different combinations of numbers that will work but always dirived from 6 8 10.

The combination I would use would depend on the size of the floor or wall I was trying to square.

6 8 10
(x2)= 12 16 20
(x1/2) =3 4 5
(x 6) =36 48 60

I havent done the math to check but 5 12 13 doesnt sound right.

It's absolutely right
5 x 5 =25
12x12=144
25+144=169
Square root of 169=13

Just remember after you 3-4-5 to double check your diagonals. If your two diagonals aren't the same measurement, you aren't square.

VERY IMPORTANT because the 3-4-5 method lends itself too easily to being somewhat inaccurate at longer distances.
