It's possible to be halfway around the Earth from the Prime Meridian ... in the Pacific
Ocean. So you can start from the Prime Meridian, and you can travel 180° East to
the Pacific Ocean, or 180° West to the same region ... total 360° of numbers to
describe your east/west position on Earth.
On the other hand, latitude is measured beginning on the equator, and you can't get
any more than 90° from the equator, north or south. If you start at the equator,
head out north or south, and travel halfway around the Earth, that brings you back
to the equator. 90° latitude puts you at one of the poles, and that's as far north or
south as you can get. So a total of 180° of latitude covers every place on Earth.
-- The northern and southern hemispheres each have 90 degrees of latitude and 360 degrees of longitude. -- The eastern and western hemispheres each have 180 degrees of latitude and 180 degrees of longitude.
Because when you travel in longitude, you can go all the way around the Earth, 360 degrees, crossing new longitudes all the way . But when you travel in latitude, the farthest you can travel is from one pole to the other pole ... halfway around the Earth, 180 degrees. Once you reach the opposite pole, if you keep going farther, you're just crossing latitudes that you've already crossed once.
Because you must go all the way around the Earth in order to cross every possible longitude, but you only need to go half-way around it ... pole to pole ... in order to stand at every possible latitude. And by the way . . . there are an infinite number of longitudes, that cover a range of 360 degrees, and an infinite number of latitudes, that cover a range of 180 degrees.
Lines of longitude (meridians) run north/south and measure angular distance east and west of the prime meridian to a maximum of 180 degrees east or west. Lines of latitude (parallels) measure angular distance from the equator. The maximum is 90 degrees north or south of the equator.
The northern and southern Hemispheres each comprise 90 degrees of latitude. On your map or globe, you're free to draw as few or as many lines as you'd like to see in that range. There is no standard set of 'lines'.
The maximum latitude is 90 degrees, you cannot have 180 degrees latitude.

360 total, 180 degrees west of prime meridian, and 180 degrees east. There are 180 degrees of latitude, 90 degrees north of the equator, and 90 degrees south.

Because there are 360 degrees in a circle. The world is assumed to be a globe that is formed from 360 degrees.
The northern and southern Hemispheres each comprise 90 degrees of latitude. On your map or globe, you're free to draw as few or as many lines as you'd like to see in that range. There is no standard set of 'lines'.
Longitude and latitude are measured in terms of degrees, minutes and seconds. Longitude has 360 degrees, while latitude 180 degrees of latitude.
360 degrees One half turn =180 degrees 180+180=360
The divisions of longitude are measured in degrees. The Earth is divided into 360 degrees of longitude, with the Prime Meridian (0 degrees longitude) serving as the starting point. Longitudes range from 0 degrees to 180 degrees east or west of the Prime Meridian, with 180 degrees being the International Date Line.
180, because a full circle is 360 degrees. 360-180=180
