Useful Mathematical Formulas:
1. One of the most useful formulas is the Pythagorean theorem. The theorem states that the square of the hypotenuse of a right (90 degree angle) triangle is equal to the sum of the squares of its legs.
For Example: (3' x 3' = 9') + (4' x 4' =16') = 25', √25=5
This can be used for a wide variety of uses from squaring up a concrete form for a foundation, to attaching a new addition squarely to an existing building, or measuring a countertop -anywhere you must be certain of a right angle. Just plug in your numbers and get a calculator that has a square root function.
