The angle of elevation and angle of depression are both measured with respect to the horizontal axis or the horizontal line. The only difference is that when an observer looks upwards at an object, then the angle of elevation is formed, while when she/he looks downwards at an object, the angle of depression is formed.

The angle of elevation is the angle between the horizontal line of sight and the line of sight up to an object. For example, if you are standing on the ground looking up at the top of a mountain, you could measure the angle of elevation. The angle of depression is the angle between the horizontal line of sight and the line of sight down to an ...

- Using Trigonometry to Solve Real-World Problems. Fares wants to find the height of a tower. He decides he needs to make a clinometer in order to measure the angle of elevation.
Angles of elevation/inclination are angles above the horizontal; angles of depression/declination are angles below the horizontal. Whenever you have one of these angles, you should immediately start picturing how a right triangle will fit into the description.
Learn how to use trigonometry to calculate angles and lengths in any triangle, using sine, cosine and tangent. See examples of problems involving angles of elevation and depression, such as estimating the height of a building or the distance to a boat.
