Triangles and your Calculator
Using the top row of keys on your ITI
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).
