The rise-over-run formula is quite literally that rise over run as that is how you would calculate the slope of a straight line joining any two points. The above equation is the Pythagorean theorem at its root where the hypotenuse d has already been solved for and the other two sides of the triangle are determined by. Learn all about the slope of a line.
The square on the hypotenuse equals the sum of the squares on the other two sides.
Formula for Calculating the Slope The length of a slope is calculated using the Pythagorean Theorem. Exclusive Content for Members Only. In this case the slope triangle is less flat. If the sides of a triangle are a b and c and c is the hypotenuse Pythagoras Theorem.
