The angle of depression from a higher point and the angle of elevation back to that point are equal because they form—
The angle of depression from a higher point and the angle of elevation back to that point are equal because they form—
- asupplementary angles
- bcomplementary angles
- calternate angles between parallel lines
- dvertically opposite angles

The observer's horizontal line and the ground are parallel, and the line of sight is a transversal, so the depression and elevation angles are equal as alternate (interior) angles.
