Step1

Start with the corner that should be square. You will be measuring along the two outer edges that form this corner.

Step2

Use the following formula:
--Mark one of the sides from the corner at 3 feet, 3 inches, 3 centimeters or 3 whatever, as long as the other measurement is of the same value.
--Mark the other side at 4 feet, 4 inches, 4 centimeters or 4 whatever (same value as other measurement).
--The distance between the two marks needs to be 5 feet, inches, centimeters or whatever (same value as other measurement).

Step3

Adjust as follows, if the distance between the two marks does not equal 5:
--If the distance between the two is less than 5, spread the two points to open up the distance.
--If the distance between the two is more than 5, tighten up the distance by bringing the two points closer together.
