What to Focus On

  • Line of sight joins the eye of the observer to the object.
  • Angle of elevation is above the horizontal line.
  • Angle of depression is below the horizontal line.

  • Surveyors use Theodolites to measure angles.
  • Theodolites were used in the great trigonometric survey.
  • Mount Everest has height 8848 meters.

  • Correct drawing is the base of the solution.
  • The horizontal line is essential in every figure.
  • Observer’s height is ignored only if not given.

Common Mistakes to Avoid

Angle of elevation and angle of depression are measured from the vertical line or from the ground, not from the horizontal line.

The height of the observer must always be ignored in every problem.

Any side opposite the angle can be called the hypotenuse.

Memory Tips

Line of sight, angle of elevation, and angle of depression

Horizontal reference line

Objects treated as linear for mathematical convenience

Height of observer is neglected if not given
