Pulled the 22 out of the garage today

[Cuda]

I was going to test fire Debbie's boat, which I've been done with for at least two months, but that's another issue.

I found this on the garage floor where I was teaching one of my guys something about tile work. Can you tell me what I was showing them?:wink:

[goatee]

basic algebra.. a squred plus b sq. = c sq.

[goatee]

cant make out the rest....was it something from road warrior?

"just walk away"

How to lay out a right angle of any size, very easily.

Looks like Pythagoras theorem to me

[Cuda]

Yes, I was showing them how to use the Pythagoreum Therom to find out if a room is square. Say you measure one foot off one wall, and pop a chalk line. Go to a wall that's 90* from that wall, make two marks, and pop another line. The go to where the two lines intersect, measure 3 feet up one line, make a mark. Then from the same spot, measure four feet up the other way and make a mark. Then I lay the tape on edge. If the room is square, the measurement between the two marks will be five feet. In a bigger room, I use 6-8-10, which also works, and is even more accurate.

Joe you are starting to scare me!

[goatee]

aaaahhh, yes...3,4,5, to the 6,8,10..would be like the difference of a pistol site to a rifle site. makes sense it would be more accurate.

When you're framing a home and use 30',40' and 50', you've got it as close as possible.
The point isn't so much the therum part, but that a triangle with legs of 3,4 and 5 units, creates a right angle.

That is in fact the Pythagorean Therom. The sum of the two legs of a triangle squared added together, equals the the hypotenuse squared. 30, 40, 50 is the same as 3-4-5, just add a zero. 300-400-500 works the same.

[maddad]

Cuda, in my mind I believe we are saying the exact same thing, but the damn computer keeps messing it up.

[tmdog]

In the 60's, we called it the 3, 4, 5, method.

That's what we still call it, or the 6-8-10.

Cuda, would you help me balance my checkbook?:)

[Last Tango]

Zero and negative numbers will never get your checkbook "balanced."

[Lenny]

Cuda, we have been doing that for years squaring Islands and Penninsulas in rooms for kitchens etc.

And slabs, and foundations, and ,.. well you know.

Once you can get to some bigger numbers you really start to make some nice, square $hit.

[Cuda]

You'd be surprised to know how many guys I've seen strike two lines, lay a framing square on it, and call it good.:confused:
