WebDefinition: Finding the Angle between Two Lines in Space Using Their Direction Cosines If ( 𝑙, 𝑚, 𝑛) and ( 𝑙, 𝑚, 𝑛) are the direction cosines for two lines in space, 𝐿 and 𝐿 , then the cosine of the acute angle, 𝜃, between the two lines is c o s 𝜃 = 𝑙 𝑙 + 𝑚 𝑚 + 𝑛 𝑛 . WebMay 6, 2015 · Find the angle of inclination of each line, using θ = tan − 1 m. (Here, θ is the angle of inclination, m is the slope.) Subtract the two angles. Handle the case where this difference is not an acute angle. (If you get a negative angle, take its absolute value. Also, when two lines intersect, they form two pairs of equal angles.
