Question

If a person is looking down at an object, then the angle the man’s line of sight makes with his eye level is the angle of __.

Answer 1

Angle of depression is the angle a person’s line of sight makes with an imaginary horizontal line at his eye level. If the person’s line of sight is below the horizontal level then it is called as angle of depression.

Or in simpler terms, if the person is looking down then we call the angle between line of sight and horizontal level as angle of depression.
