This chapter introduces new terms like the line of sight, angle of depression and angle of elevation.

  • The line of sight- It is an imaginary line drawn from the observer's eye to the object viewed by the observer.
  • The angle of elevation-  The angle of elevation of an object viewed by an observer, is the angle formed by the line of sight with the horizontal level when the object is above the horizontal level,

                             The angle of elevation

  • The angle of depression- The angle of depression of an object viewed by an observer, is the angle formed by the line of sight with the horizontal level when the object is below the horizontal level.
