you can use the old 3-4-5 rule. start at a corner and measure out 3' and mark. measure out the other way 4' and mark. then if it is square you would be able to measure diagonally and it be 5' across

You really could way over think this. No offense. Buy a laser sight level that shoots a 90 in two directions.
Triangulation is probably the least tedious most accurate method otherwise. In the suggested methods; while very valid; you'll have to do that same process at each corner.
What I find most interesting about the HUMAN element is that in the construction the corners might very well be at 90; while the linear feet may vary by fractions measuring wall to opposing wall, along its length

good answer dan, 3-4-5 or a multiple, 6-8-10, 9-12-15, etc.
But the diagonal method is most accurate. Assuming the measurements are on the same plane and the opposing sides are equal. If there is a difference in opposing sides, then the adjacent sides aren't a parallel and therefore one or both of the adjacent angles can not be square.
Geometry was one of my favorite subjects, I know pretty sad.

Just to elaborate on the 3-4-5 rule that everybody else said, just remember to use the same multiplier.
Example 3x2 - 4x2 - 5x2 and so onyou can go as high as you need to with this formula.
Also that laser square that the doc recomended is not very acurate once you get past about 10 feet, the beam gets to wide to be acurate.

3,4,5 also works in multiples of 3,4,or 5 like 6,8,10 or 9, 12,15 for larger areas
