Sheet Metal/HVAC Pro provides instant solutions in dimensional format
for Right Triangle problems for sheet metal problems.

A Right Triangle is calculated simply by entering two of four variables:

1)            (Run)

2)            (Rise)

3)            (Diagonal, or Hypotenuse); or

4)            (Theta/Pitch).

x=Run — Enters or calculates “x,” or the Run or horizontal leg (base) of a Right Triangle.

y=Rise — Enters or calculates “y,” or the Rise or vertical leg (height) of a Right Triangle.

r=Hypotenuse or Diagonal ---Enters or calculates the Hypotenuse or diagonal leg of a Right Triangle.

=Theta---Enters or calculates the Pitch (slope) of a roof (or Right Triangle).
