RIGHT-ANGLE SOLUTIONS

Your calculator's top row of keys provide you
with built-in solutions to right triangles. The
solutions are available in any of the dimensions
offered on the calculator. Thus, you can solve
right triangles directly in feet and inches, decimal
feet, decimal inches, yards, meters, centimeters
or millimeters.
You can solve for any given side if you know:
• Two other sides
• The Pitch or Bevel and one side*
• The Tangent** of the enclosed angle
(entered as Pitch) and one side
* The Pitch or Bevel is defined as the amount of Rise in 12
inches of Run. This is normally expressed in inches. However,
you can enter this in any other dimension format.
** The Tangent of the enclosed angle is defined as the Rise
side divided by the Run side of the triangle and is expressed
as a decimal i.e., in a 3 (rise)-4 (run) -5 (diag) triangle, the
Tan would be 3 ÷ 4 or .75 and would be entered as [.] 75
[Pitch].
