Find Height, Distance with Angle of Elevation, Depression using T - Ratios in Trigonometry

Angle of Elevation Angle of Depression

Trigonometry also helps in finding the height and distance of objects as well as distance between points without actually measuring these height and distances, like for example the height of mountain, width of river etc. By measuring suitable angles it is possible to calculate the height and distance

The two common terms which are used to calculate height and distance is :

  • Angle of Elevation
  • Angle of Depression

    Let's have a look at the below picture to understand the Angle of Elevation and Depression



    In the above picture an observer is standing on a hill, so
  • Green line is the horizontal line
  • Blue lines are observer line of sight
  • Red curve lines represents angles made
  • The angle made when the observer looks at the airplane is Angle of Elevation
  • The angle made when the observer looks at the ship is Angle of Depression

    To find height and distance using angle of elevation and angle of depression you can study the above links
