# Angle of elevation and depression

The angle of elevation is the angle that the line of vision makes with the horizontal line, if the object is above the line of vision when the object is below the line of vision, then the angle that the line of sight makes with the horizontal is referred to as the angle of depression [. Angles of elevation and depression help us find distances between things like radar stations to planes, lighthouses to buoys two boats at sea and more. Angles of elevation and depression are used in measuring heights and distances in trigonometric applications using right triangles these angles are made when we look up or down to view objects devices are available to measure angles of elevation and depression these measured angles can be used in measuring. Questions involving trigonometry often involve angles of elevation and depression the following videos will explain to you what angles of elevation and depression are and show you how to approach these types of problems key to success is, as always, to draw a diagram of the situation and to clearly label your angles.

Sohcahtoa, pythagoras, sine rule and cosine rule and all things trigonometry actually have a lot of uses in “real life” such as working out distances to things, heights of buildings and mountains, navigation at sea an important part of “ useful” trigonometry are angles of elevation and depression if you're. Suppose that you are looking at an object in the distance if the object is above you, then the angle of elevation is the angle your eyes look up if the object is below you, the angle of depression is the angle your eyes look down angles of elevation and depression are measured from the horizontal it is common mistake not.

The term angle of elevation denotes the angle from the horizontal upward to an object an observer's line of sight would be above the horizontal. Find distance using right triangles and angles of elevation or depression. Learn what the terms angle of elevation and angle of depression mean the words may be big but their meaning is pretty basic.
