Define : (a) line of sight
(b) angle of elevation
(c) angle of depression
Answers
Answer:
The angle of elevation is when you are measuring the angle from the floor or the ground, and the angle of depression is when you are measuring from a ceiling. The only time the two angles are equal is if the ceiling and floor are parallel with each other. If you know your angle terms these are opposite interior angles
Answer:
line of sight
the line between two points specifically : the straight path between a transmitting antenna (as for radio or television signals) and a receiving antenna when unobstructed by the horizon.
angle of elevation
The angle of elevation is an angle that is formed between the horizontal line and the line of sight. If the line of sight is upward from the horizontal line, then the angle formed is an angle of elevation.
angle of depression
The angle of depression is the angle between the horizontal line and the observation of the object from the horizontal line. It is basically used to get the distance of the two objects where the angles and an object's distance from the ground are known to us.
