The terms angle of depression and angle of elevation refer to the angles at which an observer must direct their line of sight in order to see an object. What is the difference between an angle of elevation and angle of depression hi anjum, if you are looking at an object above the horizon then the angle between the horizontal and your line of sight is the angle of elevation. Surveyors use two instruments, the transit and the theodolite, to measure angles of elevation and depression on both instruments, the surveyor sets the horizon line perpendicular.
How do you find the tangent of an angle in a right triangle a trigonometric ratio is a ratio between two sides of a right triangle the tangent ratio is just one of these ratios. Angles of elevation and depression please view this tutorial and answer the follow-up questions on loose leaf to turn in to your teacher how to interpret word problems into right triangles. Angle of elevation - the angle between a diagonal line (moving 'upward') and a straight horizontal line differs from angle of depression in that the angle formed is above the horizontal line. The angle of elevation or depression is the angle between the horizontal ( parallel with the earth's page 3 sketch a diagram to support your answer.

Learn what the terms angle of elevation and angle of depression mean the words may be big but their meaning is pretty basic. Then if is above , the angle ∠ is the angle of elevation of observed from , and if is below , the angle ∠ is the angle of depression often when using angle of elevation and depression we ignore the height of the person, and measure the angle from some convenient 'ground level. Angle of elevation the upwards angle from the horizontal to a line of sight from the observer to some point of interest if the angle goes downwards it is called an angle of depression.
