The angle below horizontal that an observer must look to see an object that is lower than the observer. Note: The angle of depression is congruent to the angle of elevation (this assumes the object is close enough to the observer so that the horizontals for the observer and the object are effectively parallel; this would not be the case for an astronaut in orbit around the earth observing an object on the ground).

How do you find angle of depression?
The angle of depression of a point is the angle between the line joining that point and the point of observation and the horizontal from the point of observation.
What does angle of depression in geometry mean?
It is the alternate angle to the angle of elevation
What is angle of Depression?
Angle of depression is the angle between a horizontal line and the line joining the observer's eye to some object beneath the horizontal line. ^_^
What is the angle of measurement below a horizontal line called?
angle of depression.
About how long is a shadow of an 80 ft tall oak tree if the angle of the sun is 40 degrees?
It depends on the angle of depression of the sun. The answer would be 80ft * tan(90-angle of depression) At a depression angle of 40 degrees, the shadow would be 80 * tan (50) which equals 95.340ft
