## How do you find the angle between two lines?

The angle between two lines can be calculated from the slopes of the lines or from the equation of the two lines. The simplest formula to find the angle between the two lines is from the slope of the two lines. The angle between two lines with slopes m1 m 1 , and m2 m 2 respectively is Tanθ = m1−m21+m1.

## What is the formula for angle between two lines?

We will learn how to find the angle between two straight lines. Let the equations of the straight lines AB and CD are y = m1 x + c1 and y = m2 x + c2 respectively intersect at a point P and make angles θ1 and θ2 respectively with the positive direction of x-axis. Let ∠APC = θ is angle between the given lines AB and CD.
