➢ the angle that a line makes with a horizontal line which has a measure of not more than 180 °.
The angle inclination of a line is the angle formed by the intersection of the line and the x-axis. Using a horizontal "run" of 1 and m for slope, the angle of inclination, theta=tan-1(m), or m=tan(theta).
