If a person stands and looks up at an object, the angle of elevation is the angle between the horizontal line of sight and the object. If a person stands and looks down at an object, the angle of depression is the angle between the horizontal line of sight and the object. Trigonometry can be used to solve problems that use an angle of elevation or depression. A man is 1. He stands 50 m away from the base of a building. Calculate an estimate of the height of the building.

In the diagram below, AB is the horizontal line. What is angle of depression? The angle of depression is the angle between a horizontal line from the observer and the line of sight to an object that is below the horizontal line. In the diagram below, PQ is the horizontal line. In the diagram below, AB and CD are two vertical poles on horizontal ground. Draw in the angle of elevation of D from B and the angle of depression of C from B.
