Inclination of a Line | Angle Between Two Lines | Distance Between a Point and a Line

In this lesson, we will learn how to find the inclination of a line by setting the tangent of θ equal to our slope, m. We will then use our inverse tangent function to find our θ in quadrant I. When we are in quadrant II, we need to add 180° to the result. Additionally, we will learn how to find the angle between two lines and how to find the distance between a point and a line.
