Question

why tan value of angle is taken as the slope?why not any other ratio?

Answer 1

slope is actually Rise/Run=perpendicular/base=tantheta=slope

Answer 2

Heya user !!!

Here's the answer you are looking for

Slope is the ratio of the rise and run of the line.

Rise means the perpendicular distance of the line from x - axis and run means the perpendicular distance from y - axis.

Rise / Run = Perpendicular / base = tanA

Therefore, tan is only taken into consideration when we have to find the slope of a straight line.
