The Prime Meridian is a line of longitude, and it sits at 0 degrees longitude.
-- All lines of longitude meet at the north and south poles. -- No two lines of latitude ever meet or cross each other. -- Every line of longitude crosses every line of latitude. -- Every line of latitude crosses every line of longitude. -- There are an infinite number of each kind, so there are an infinite number of places where a line of longitude crosses a line of latitude. (That's kind of the whole idea of the system.)
-- Each meridian ( 'line' ) of longitude represents all of the infinite number of points on the Earth's surface that have that one specific longitude. -- Each parallel ( 'line' ) of latitude represents all of the infinite number of points on the Earth's surface that have that one specific latitude.
The major line of longitude located at 180 degrees longitude is the International Date Line.
The equator is not a longitude line. It is a circle that divides the Earth into the Northern and Southern Hemispheres. Longitudes are vertical lines that run from the North Pole to the South Pole on the Earth's surface.
The smallest is 0o0'0'' and the largest is 180o0'0''
Longitude is the number of degrees east or west along a line of latitude from the prime meridian.
Go from left to right along the number line.
The largest number minus the smallest number.
The 180 degree longitude is often miscalled international date line, when it is actually called the Anti Meridian.The date line is not a meridian or line of longitude because it is not a straight line as it deviates to separate geographical places, certain island groups for instance.See the link below for an image.The longitude that runs through Greenwich England is the prime meridian, which is 0 deg longitude.
The Prime Meridian is a line of longitude, and it sits at 0 degrees longitude.
That completely depends on what line it's opposite from.
Coordinates given in WikiPedia indicate a longitude of 21 degrees east. This puts the point at which this coordinate is set east of the 20 degree line.
Every longitude on Earth forms a line between the north and south poles. Name any number from zero to 180, then call it east or west, and you have a different longitude.

That's a line that joins the north and south poles, called the Prime Meridian.
