Question

lesson 3: drilling for understanding

1. label the angle of elevation (a) and angle of depression (d) in the following diagrams.

note: you need to label only two of the angles.
a.
b.

Explanation:

• Angle of elevation: It is the angle formed between the horizontal line of sight and the line of sight when looking up at an object.
• Angle of depression: It is the angle formed between the horizontal line of sight and the line of sight when looking down at an object.

Answer:

• For part a:
• The upper - most non - right angle (the angle above the horizontal line) is the angle of elevation (\(a\)).
• The lower - most non - right angle (the angle below the horizontal line) is the angle of depression (\(d\)).
• For part b:
• The upper - most non - right angle (the angle above the horizontal line) is the angle of elevation (\(a\)).
• The lower - most non - right angle (the angle below the horizontal line) is the angle of depression (\(d\)).
