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: • 2 5 Í*
• A percent grade: 2 5 Ç Í
• A slope angle: 5 Ç 8 Í
*This represents a 4:1 slope ratio (e.g.,
4 Ç
÷ Í
).
Slope =
Depth
Width
