The vertices of the Celestial Triangle correspond to which of the following in the Navigational Triangle?

In celestial navigation, the vertices of the Celestial Triangle directly correspond to specific locations or points relevant to understanding and calculating positions in the Navigational Triangle. The correct answer highlights the relationship with the North or South Pole, the Assumed Position (AP), and the Geographic Position (GP).

The North or South Pole serves as one vertex in the Celestial Triangle, representing the reference point from which celestial objects are observed. The Assumed Position is the location where the navigator presumes their vessel is at a given time for the sake of calculations, and it plays a crucial role in determining accurate bearings and distances when navigating.

Finally, the Geographic Position is the actual location of the observer, which is essential to understand where they stand in relation to celestial bodies and their observed positions in the sky. This triangle of points helps navigators relate celestial observations directly to their position on Earth.

In contrast, other options listed do not accurately depict the correspondence of triangles in celestial navigation. For example, focusing on the Zenith or Horizon in the context of a celestial triangle introduces points that are less relevant to the relationships formed with the celestial bodies being observed. Each vertex of the celestial triangle must directly be tied to the navigational aspects of celestial navigation, which is vital for accurate positioning
