  • What are the first and second steps in identifying the angle of elevation and the angle of depression?
    1. Identify the horizontal line of sight.  2. Identify whether the given object is above or below the horizontal line of sight.
  • It is an imaginary line that starts at your eyes and moves out horizontally, parallel to the ground.
    Horizontal line of sight
  • A
  • It is an imaginary line that connects the eye of an observer to the object being observed.
    Line of sight
  • B
