The northern hemisphere is the half of the Earth north of the equator, and the southern hemisphere is the half south of ... Simple geometry shows that the angle between the zenith and the celestial equator (i.e. the zenith's declination) must also be the angle between the north celestial pole and the north horizon.

The extension of this line an infinite distance locates the north celestial pole (NCP). The angle between your location on the Earth's surface and the north geographic pole is 90 - L (This is called your colatitude). ... From the diagram, note that the angle between the rotational axis and the line parallel to your horizon,

in fact the angle between zenith and that crossing point is also equal to the observer's latitude. ... In the southern hemisphere (i.e., the observer's latitude is negative) the north celestial pole is below the northern horizon by an angle equal to the absolute value of the observer's latitude. (Note: negative latitude;
