How to Find Angle of Depression
To find the Angle of Depression for any given condition, we construct a right-angle triangle by drawing perpendicular, and in that right-angle triangle one of the angles is the angle of depression. To find the angle of depression we use the given sides of the triangle and trigonometric ratios and the following steps.
Step 1: Observe the given sides of the triangle.
Step 2: If the perpendicular and hypotenuse of the triangle are given then we use the trigonometric ratio sin.
Step 3: If the base and hypotenuse of the triangle are given then we use the trigonometric ratio cos.
Step 4: If the base and perpendicular of the triangle are given then we use the trigonometric ratio tan.
Step 5: Now, calculate the angle of depression using one of the appropriate formulas as given below:
- θ = sin-1(p/h)
- θ = cos-1(b/h)
- θ = tan-1(p/b)
Therefore, the resultant value will give the angle of depression.
Angle of Depression
Angle of Depression is one of the two important angles in Trigonometry, the other being the angle of elevation. The angle of depression refers to the angle at which one must look downward from a horizontal position to view an object situated at a lower level. It’s defined by the direct line from the observer to the object being observed, indicating a downward inclination of the line of sight.
In this article, we will learn about the Angle of Depression including various examples of the angle of depression and key differences between the angle of elevation and the angle of depression. We will also learn, how to calculate the angle of depression.
