Chapter 4: Problem 4

Fill in the blanks. An angle that measures from the horizontal upward to an object is called the angle of _____, whereas an angle that measures from the horizontal downward to an object is called the angle of _____.

Short Answer

Expert verified
The angle of elevation is measured from the horizontal upward to an object whereas the angle of depression is measured from the horizontal downward to an object.

Step by step solution

01

Identifying the Upward Angle

The angle that measures from the horizontal upward to an object is called the angle of 'elevation'. In other words, it's the angle formed between the line of sight when looking upwards (towards the object) and the horizontal direction.
02

Identifying the Downward Angle

On the other hand, the angle that measures from the horizontal downward to an object is termed as the angle of 'depression'. That is to say, it's the angle formed between the horizontal direction and the line of sight when looking downwards.
