Step 1 :An angle of elevation is the angle formed between a horizontal line and the line of sight when looking up at an object.
Step 2 :An angle of depression is the angle formed between a horizontal line and the line of sight when looking down at an object.
Step 3 :Diagram for angle of elevation:
Step 4 :\(\begin{array}{c} \text{Angle of Elevation} \\ \text{A} \\ \text{/|} \\ \text{/ |} \\ \text{/ |} \\ \text{/ |} \\ \text{/ |} \\ \text{B /_____| C} \end{array}\)
Step 5 :Diagram for angle of depression:
Step 6 :\(\begin{array}{c} \text{Angle of Depression} \\ \text{A _____ B} \\ \text{\ \ \ \ \ \ |} \\ \text{\ \ \ \ \ \ |} \\ \text{\ \ \ \ \ \ |} \\ \text{\ \ \ \ \ \ |} \\ \text{\ \ \ \ \ \ |} \\ \text{\ \ \ \ \ \ C} \end{array}\)
Step 7 :\(\boxed{\text{The angle of elevation is the angle formed between a horizontal line and the line of sight when looking up at an object, while the angle of depression is the angle formed between a horizontal line and the line of sight when looking down at an object.}}\)
