Procedure:
Activity : Look Up and Look Down
- When you see an object above you(Looks up),there is an angle of elevation between the horizontal and your line of sight to the object.
- When you see an object below you(Looks down),there is an angle of depression between the horizontal and your line of sight to the object
- Identify the segment that represents the line of sight.
- Identify the angle that represent the angle of elevation or angle of depression.
