Angle of Depression
When an object or point is located below the horizontal level, the angle formed by the line of sight with the horizontal is called the angle of depression. This angle is measured downwards from the horizontal line to the line of sight.
Explanation:
1. Angle of Elevation:
The angle of elevation is the angle formed by the line of sight with the horizontal when the point is located above the horizontal level. It is measured upwards from the horizontal line to the line of sight. This angle is commonly used when determining the height of an object or the angle at which an object is observed from a higher point.
2. Angle of Depression:
In contrast, the angle of depression is formed when the point of observation is below the horizontal level. It is measured downwards from the horizontal line to the line of sight. This angle is commonly used when determining the depth or height of an object or the angle at which an object is observed from a lower point.
Example:
Imagine standing on a cliff and looking down at a boat on the water. The line of sight from your eyes to the boat forms an angle with the horizontal. This angle is the angle of depression because the boat is below the horizontal level.
Summary:
In summary, the angle formed by the line of sight with the horizontal when the point is below the horizontal level is called the angle of depression. It is measured downwards from the horizontal line to the line of sight and is used to determine the depth, height, or angle of observation from a lower point.
