What is the Pythagorean theorem (A

2 +B 2 =C 2 ), and how do I use it for duct layout? It is a math formula used to find the unknown side of a right triangle. In duct installation, it is used daily to calculate long diagonal offsets for spiral pipe runs, to build exact transition pieces, or to verify that a large rectangular layout or room corner is perfectly square (90 ∘ ) by testing the diagonal cross lengths.
