Angles Of Elevation and Depression:

Angle of Elevation:

When a person looks at something above his or her location e.g (The top of a building). The angle formed between the horizontal ground and the line of sight is called the angle of elevation.

Angle Of Depression:

When a person looks at something below his or her location, the angle between the imaginative horizontal and vertical and the line of sight is the angle of depression.

Angle of depression is always of equal value as angle of depression because they are alternative angles.
