En el triángulo de posición, el ángulo formado por los lados de la colatitud y la codeclinación es:In the navigational triangle, the angle formed between the colatitude side and the codeclination side is:
Show the answer
Correct answer: b) The angle at the pole (meridian angle P).
Why it is correct
In the navigational triangle (PZX), the colatitude side (PZ, along the observer’s upper meridian) and the codeclination/polar-distance side (PX, along the body’s hour circle) meet at the elevated pole (P), forming the polar or meridian angle (P).
Why the others are not
- a) The parallactic angle is formed at the body (X), between the codeclination and zenith-distance sides.
- c) The azimuth angle is formed at the zenith (Z), between the colatitude and zenith-distance sides.
- d) Sidereal hour angle is measured from Aries and is not an interior angle of triangle PZX.
How to work it out in the exam
- Angle between colatitude (PZ) and codeclination (PX): the polar angle (P).
