The north pole is 90 degrees north latitude. The south pole is 90 degrees south
latitude. When you travel from one pole to the other, you go through 180 degrees
of latitude. Which isn't so surprising, since that trip takes you halfway around the world.
There are 180 degrees between the North and South Poles.
(That trip is halfway around the sphere.)
There are 180 degrees between the North and South Poles.
(That trip is halfway around the sphere.)
That trip is half-way around a sphere (the Earth).
Halfway around anything is 180°. Latitude is no exception.
Those two points are literally "poles apart" as the saying goes. 90 North is the north pole. 90 South is the south pole.
-- Each degree of latitude, anywhere on Earth, is about 69 miles in a north or south direction. -- Each degree of longitude covers a different distance, depending on the latitude. At the poles, any number of degrees of longitude cover zero distance.
The Earth is not a perfect sphere, and the WGS84 system that we use for degree confluences includes a mathematical model (GRS80) of the Earth as an ellipsoid. Using established GRS80 constants, and the Vincenty Algorithm (PDF document), the distance between degrees of latitude (lines that run east-west) varies from 110.57km (68.71mi) at the equator (0 degrees latitude) to 111.69km (69.40mi) between 89 degrees latitude and the poles. For the purposes of the project, we don't take these variations in the distance between degrees of latitude into account when categorizing degree confluences. Using the same calculation methods, the distance between degrees of longitude (lines that run north-south) varies between 111.32km (69.17mi) at the equator (0 degrees latitude) to 1.95km (1.21mi) at 89 degrees latitude, one degree from the north or south pole. Because the lines of longitude meet at the poles, the distance between degrees of longitude at the poles is zero.
The North Pole is at 90 degrees N latitude, the South Pole is at 90 degrees S latitude. A total of 180 degreed. All lines of longitude converge at both the North and South Poles.
-- Since you're asking for "parallels", we know that the discussion concerns latitude.-- The total extent of latitude on the Earth is 180 degrees.-- The north and south poles are degenerate "parallels", i.e. circles with zero radiusat 90 degrees north and south latitude.-- If we draw in all the rest of the parallels between the poles at intervals of5 degrees, we'll need to draw 35 of them.
The equator is on the 0 degree latitude that is between the north and south poles. So obviously it is between the poles.
The North Pole has a latitude of 90 degrees N, and the South Pole has a latitude of 90 degrees S.
90 ... at the north and south poles.
There are 180 degrees of latitude between the poles.

The two parts where the maximum degree of latitude is reached are the North Pole, at approximately 90 degrees north latitude, and the South Pole, at approximately 90 degrees south latitude.

The Geographic Poles are just points; 90 Degrees North or South Latitude.
