POCKET REFERENCE GUIDE — 24
RIGHT TRIANGLE PROBLEMS
The calculator’s top two rows of keys
include built-in solutions to Square-up,
Drop, Percent Grade and Slope problems.
Square-up is calculated from the values
entered as Length and Width.
Slope and Percent Grade are calculated
using the values for Width and Height
(Depth).
A slope can be entered as:
• A Slope Ratio: •25Í*
• A percent grade: 25ÇÍ
• A slope angle: 5Ç8Í
*This represents a 4:1 slope ratio (e.g., 4Ç
÷Í).
Slope =
Depth
Width
