👉 Underslope is a term in mathematics that describes the angle of inclination between the horizontal and the line of slope. It is defined as the angle of elevation from one point to another, measured along the line of slope. The underslope is calculated by subtracting the vertical distance from the top of the first line from the vertical distance from the bottom of the second line. This difference gives the angle of inclination between the two lines. For example, if a person stands at point A and walks 1
