What to Focus On

  • Trigonometric ratios are used for indirect measurement.
  • The problems are 2-D and involve right-angled triangles.
  • Angles of elevation and depression are measured from a horizontal line.

  • The object is above the horizontal line.
  • The observer looks upward.
  • The angle is formed by the line of sight and the horizontal line.

  • The object is below the horizontal line.
  • The observer looks downward.
  • The angle is formed by the line of sight and the horizontal line.

Common Mistakes to Avoid

Any angle made by a line of sight is an angle of elevation.

Angle of depression is measured from the ground, not from the horizontal line.

The same angle can be used for elevation and depression without checking which point is above or below.
