You've spelt curious wrong.
The builder supplies 3 bricks 4 the price of 5
3 4 5 is a very useful method and very accurate, use it all the time
3,4,5 is kinda bullet proof - but the method 'can' be extrapolated and used slightly differently. If you know the depth of your proposed extension (a) and the width (b) - you can calculate the hypotenuse of this triangle (c). You can then draw a tape measure out from a predetermined point on your existing building and mark an arc on the floor at distance (a). You can then draw a tape out from the existing building again, only this time from a point that is the width of the extension from (a), i.e. (b). From this point, you run the tape diagonally over towards the small arc you made at step one. Where the length of (c) crosses (a) you have perfect right angle at the perfect distance. Repeat for the other corner.
I've made it sound very complicated, but in reality its very easy.
