It doesn't sound like Morton. And I'm sure they'll make it right.
Remember in school A squared plus B squared equal C Squared?
If you want to check square on a corner pull some measurements on two intersecting walls. Three four five is a good one. Measure down three feet down one wall, make a mark. Measure down the other wall four feet, make a mark.
It should measure five feet diagonally between the marks.
You can use any variation of this, six eight ten etc.
Laying out a slab or fence is much easier this way than the old move the diagonal technique, especially if like me one is working by himself.
You take each side and multiply it by itself. Then you add those two numbers together. Sixty by a hundred foot would be thirty six hundred plus ten thousand. The square root of thirteen thousand six hundred is one hundred sixteen feet and six tenths of an inch. That's your're diagonal measurement.
Working by yourself you'd find one plane. Let's say it's the hundred foot line and you want that line to be parallel to the road, the house, whatever. You make those marks a hundred feet apart.
Then go out sixty feet as close to perpidicular to the hundred foot line as experience and common sense will allow. Make a mark. From the opposite corner or hundred foot mark pull off one hundred and sixteen feet and six tenths of an inch. Where the sixty foot mark and the diagonal one meet is your squared corner of that end of the building or fence.
To find the last corner measure down one hundred feet from your found corner and up sixty feet from the far corner. You can do a double diagonal measurement for excerise or self satisfaction. It will be dead on.
If you do this with a kid that's having problems in math in school but he loves making things. He or she will find a whole new reason to pay attention from now on in math classes. /forums/images/graemlins/grin.gif
If like me your math teacher was an old gal you could call this a "biddy ditty".
