Info: Making a square
If you want to make a bigger square remember this the 3:4:5 rule.
Say we use a 3 straight lenght of 2"x1", lay all timber down as a triangle shape and on the external point, 1 must be 3 foot,1 must be 4 foot and the last one meet up must be 5 foot.You will always get 90 degree.Doesn't matter what measurement you use (3cm,4cm,5cm or 3miles,4miles,5miles!)Very handy for laying out garden project or fitting a corner bath or footing and so on.Try experiment on a A4 paper marking 3" from one corner & 4" on the other side from the same corner and put a ruler across the 2 points ,it will 5" and that will always be 90 degree square.
