Answer» 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.
Observe the figure. Consider the observer to be at point C. The height of the object is shown by line AB. The distance of the object from the observer is given by line BC. The object may or may not be PERPENDICULAR to the ground. Line AC REPRESENTS the Line of Sight when the observer is observing the topmost point of the object. Angle α represents the angle of elevation and Angle β represents the angle of depression |
