Answer:
hematics. It often fetches some direct questions in various competitions like the IIT JEE. Since the topic is quite vast, students are advised to spend sufficient time on grasping the various concepts. Angle between pair of straight lines is an important head under straight lines. We begin with the concept of angle between pair of lines and then discuss some of the illustrations on the same:
Angle between two Straight Lines
Suppose we have two straight lines y = m1x + c1 and y = m2x + c2, then the angle between these two lines is given by tan θ = |(m1 – m2)/ (1 + m1m2)|.
If m1, m2 and m3 are the slopes of three lines L1 = 0, L2 = 0 and L3 = 0, where m1 > m2 > m3 then the interior angles of the triangle ABC formed by these lines are given by,
tan A = (m1 - m2)/(1 + m1m2), tan B = (m2 - m3)/(1 + m2m3) and tan C = (m3 - m1)/(1 + m3m1).
Step-by-step explanation:
