Slope distance (2D)

Treat run and rise as the legs of a right triangle to get slope length, grade in percent, and angle in degrees — handy for ramps, banks, and bore alignment sketches.

Right-triangle slope

Use the same horizontal units for run and vertical units for rise (feet with feet is typical). Slope length is the hypotenuse.
