8 — Construction Master IV
Right Triangle/Rafter Keys
[Pitch]
This key is used to enter or calcu-
late the pitch (slope) of a roof (or
right triangle). Pitch is the amount
of "Rise" over 12 inches (1 meter, if
metric) of "Run." Pitch may be en-
tered as:
a dimension
9 [Inch] [Pitch]
an angle
30 [Pitch]
a ratio
0.75 [Conv] [Pitch]
a percentage
75 [%] [Pitch]
A pitch entry will remain in perma-
nent storage until revised or reset. A
solution will be replaced by its en-
tered value once the calculator is
cleared.
[Rise] — Rise Key
Enters or calculates the rise or ver-
tical leg (height) of a right triangle.
[Run] — Run Key
Enters or calculates the run or hori-
zontal leg (base) of a right triangle.
