The ___________ of an object is the angle formed by the line of sight ...
The angle of depression is the angle formed by the line of sight with the horizontal when the object is below the horizontal level. This is commonly observed when looking downward from a higher point to a lower point.

The ___________ of an object is the angle formed by the line of sight ...
Angle of Depression:
The angle of depression refers to the angle formed by the line of sight with the horizontal when the object is below the horizontal level. It is an important concept in geometry and trigonometry.
Line of Sight:
The line of sight is the imaginary line that connects an observer's eye with the object being observed. It represents the direction in which the observer is looking.
Horizontal Level:
The horizontal level refers to a straight line that is parallel to the horizon. It is a flat, level line that does not slope or tilt.
Explanation:
When an object is below the horizontal level, the line of sight from the observer's eye to the object will be inclined downwards. This downward inclination creates an angle with the horizontal level. This angle is known as the angle of depression.
The angle of depression is measured from the horizontal level downwards towards the object. It is always measured in relation to the horizontal level, not the vertical level. The angle is usually measured in degrees or radians.
The angle of depression can be used to determine the height or depth of an object or location. By measuring the angle and knowing the horizontal distance between the observer and the object, trigonometric principles can be applied to calculate the vertical distance.
For example, if an observer standing on a cliff looks down at a boat on the water, the angle of depression can be measured. By knowing the horizontal distance between the observer and the boat, the vertical distance between the observer and the boat can be calculated using trigonometry.
In summary, the angle of depression is the angle formed by the line of sight with the horizontal when the object is below the horizontal level. It is an important concept in geometry and trigonometry and is used to calculate heights and depths of objects or locations.
