III. Identify the segment that represents the line of sight and identify the angles (if any) that represent the angle of elevation or angle of depression.

The angle of elevation is the angle formed between a horizontal line and the line of sight when an observer looks upwards at an object or point of interest.

The angle of depression is the angle formed between a horizontal line and the line of sight when an observer looks downwards at an object or point of interest.

Question 1

The image shows a person looking down at an object on the ground. Therefore:

Angle of Depression = ∠DEF
Line of sight DF

Question 2

The image shows a person looking up at the ball. Therefore:

Angle of Elevation = ∠GHI
Linge of sight = HG

Question 3

The image shows a person looking down at an object on the ground. Therefore:

Angle of Depression = ∠KLJ
Line of sight = LJ

Question 4

The image shows a person looking down at a dog. Therefore:

Angle of Depression = ∠MON
Line of sight = ON

Question 5

The image shows a person looking up at the top of the tree. Therefore:

Angle of Elevation = ∠RQP
Line of sight = QR

III. Identify the segment that represents the line of sight and identify the angles (if any) that represent the angle of elevation or angle of depression.​
