Travelling all the way around the Earth from the the Prime Meridian (0°) takes you in a circle of 360°
Therefore, at the exact opposite side of the Earth as the prime Meridian is 180°.
Longitude is measure from 0° to 180° either East or West of Greenwich so it ends at 180°.
Since the earth is a sphere (ball), you can reach any place on earth by traveling in either direction from any other place. To reach any west longitude from the Prime Meridian, heading west is the shorter way. To reach any east longitude from the Prime Meridian, heading east is the shorter way.
The largest angle that can be measured in any direction from any point on earth is 180 degrees.Since there are 360 degrees all around, once you pass 180, it's shorter to go around the other way.
the Prime Meridian or Greenwich Meridian and runs through Greenwich England ________________________________ You're probably thinking of the Prime Meridian, but the Prime Meridian doesn't circle the Earth; it only covers half of the Earth. The other half of the circle is the "anti-meridian" at longitude 180 degrees. (East or west? Both, and neither.)
There is no difference between 180 degrees east and 180 degrees west longitude because the Earth is divided into the eastern and western hemispheres, each having 180 degrees of longitude each. Therefore, 180 degrees east and west longitude means the same thing --- 180 degrees longitude.
The longitude of every point on the Prime Meridian is Zero.
If two travellers 'A' and 'B' started from the Prime Meridian (zero longitude). 'A' travelled to the West, and ''B travelled to the East, they will meet on the other side of the World at 180 degrees longitude. Therefore, the biggest number is 180 degrees longitude. The International Date Line roughly follows the 180 degrees longitude north-south line on the Earth.

The Prime Meridian passes through Greenwich, England. It is designated as 0 degrees longitude and all other meridians are measured in degrees east or west of it. The Prime Meridian was established for navigation and is the basis on which International time is kept.
Some of the people who regularly use latitude and longitude in their jobs are: geographers, cartographers, members of the Armed Services or military, geologists, aviators, travel agents, historians and social studies teachers.

There is an infinite number of possible longitudinal lines. But the total number of degrees is 360; 180 east and 180 west. There are 60 minutes in a degree and 60 seconds in the minute. How you sub-divide from there gives infinite possibilities. There are usually 36 lines of longitude on the globe or a map, located at 10 degrees longitude apart.
Since a set of latitude/longitude coordinates defines a single point on the Earth's surface ... with no length, width, or area ... it's not possible for an entire state to be right there. That point is in the Baxter State Park in the state of Maine. There are a huge number of other points, all with different latitudes and longitudes, that are also in the state of Maine.
The Earth rotates approximately 15 degrees in one hour. This is determined by dividing the number of degrees in one full rotation (360) by the number of hours in one day. Of the other planets in the solar system, Mars is the most similar to Earth in terms of degrees rotated in one hour.
