Question

define the angles of Intersection​

Answer 1

Answer:

The angle θ is the angle of the intersection of lines l1 and l2 measured from l2 to l1. ... The angle ψ is also the angle of intersection of lines l1 and l2 measured from l2 to l1. If the lines are not perpendicular, then one angle between them is an acute angle.
