Rescaling the Pythagorean Theorem
The Pythagorean theorem can apply to any shape, not just triangles. It can measure nearly any type of distance. And yet this 2000-year-old formula is still showing us new tricks.
Re-arranging the formula from this:

to this:

helps us understand the relationship between slope (steepness) and distance. Let’s take a look.
