Show the answer
Correct answer: a) The codeclination (polar distance).
Why it is correct
The side of the navigational triangle connecting the observer’s elevated pole (P) and the celestial body (X), measured along the body’s hour circle, is the polar distance or codeclination (90° ± δ).
Why the others are not
- b) Zenith distance is the side between the zenith (Z) and the body (X).
- c) 90° − altitude is the zenith distance (side ZX).
- d) Both b) and c) define the zenith–body side, not the pole–body side.
How to work it out in the exam
- Pole–Body side (PX): codeclination or polar distance.
