Right Triangle/Roof Framing Keys
Right Triangle:
Diagonal
Run
Rise
Using the Pythagorean theorem, the top row of keys on your
Construc-
tion Master Pro provide instant solutions in dimensional format to right
triangle problems (particularly, roof framing).
The
Construction Master Pro’s keys are labeled in easy to remember
roofing terms. The right triangle is calculated simply by entering two of
four variables: 1) Rise, 2) Run, 3) Diagonal or 4) Pitch.
[Pitch]
Enters or calculates the pitch (slope) of a roof (or right triangle).
Pitch is the amount of "rise" over 12 inches (or 1 meter) of "run."
Pitch may be entered as:
•
a dimension: 9 [Inch] [Pitch]
•
an angle: 30 [Pitch]
•
a ratio: 0.75 [Conv] [Pitch]
•
a percentage: 75 [%] [Pitch]
