East 180 to west 180.
Lines of Longitude are imaginary lines that run from the North Pole to the South Pole. The main line of longitude, the Prime Meridian (zero longitude), passes through the Greenwich Observatory, London, England.
The Prime Meridian is a line of longitude (0°). It goes through every north or south measurementbetween the north pole and the south pole, and no other lines of longitude cross it.
Imaginary lines that run north to south are known as lines of longitude. Longitude lines are the imaginary lines running through the Earth between the North and South Poles. They are arbitrary and used for reference so everyone can know where they are in the world. The lines running north and south are called "meridians" or "lines of longitude."
Lines of longitude meet at the North and South Poles.
The key lines are latitude and longitude. These are based on specific points. The equator is the latitude around the center of the earth. Longitude is measured from the Prime Meridian, which goes through the Greenwich Observatory in England.The Tropics and the Arctic/Antarctic Circle are also key.
Every meridian of constant longitude joins the north pole to the south pole.

Longitude
The North/South lines on the geographic grid are named 'Lines of Longitude' or 'Meridians'. The 'Zero' line passes through Greenwich Observatory in London, England. This position was fixed historically, some 350 years ago, by Astronomers and navigators of the day, and has remained so to this day. The 180 degrees line of longitude passes through the Pacific Ocean, and for most of its course it is also the International Date Line.
Lines of longitude stay right there where they are at. Each of them connects the north and south poles.
