The imaginary line is called the Prime Meridian.
"parallels" of latitude
parallels of constant latitude
That is called the 'Prime Meridian'.
-- Parallels are associated with latitudes. Meridians are associated with longitudes. -- Parallels are parallel, and no tweo parallels intersect. All meridians intersect all other meridians, at two places. -- Every point on a parallel has the same latitude. Every point on a meridian has the same longitude. -- Every parallel in the same hemisphere has a different length. Every meridian on Earth has the same length. -- Every parallel is a full circle. Every meridian is a semi-circle. -- Every parallel crosses all longitudes. Every meridian crosses all latitudes. -- The distance between two parallels is the same at every longitude. The distance between two meridians depends on the latitude where it's measured. -- To cross all parallels, you only have to travel 12,000 miles. To cross all meridians, you have to travel 24,000 miles.

A "parallel" is a line comprised of all the points on Earth with the same latitude ... the angle measured north or south of the equator. Each parallel is a full circle, that crosses all meridians. A "meridian" is a line comprised of all the points on Earth with the same longitude ... the angle measured east or west from the Prime Meridian. Each meridian is a half- circle, that crosses all parallels.
Parallels Parallels are circles that are parallel to the equator. They are measured in degrees north or south of the equator, with 0° latitude being the equator itself. The distance between two adjacent parallels decreases as you move towards the poles. The equator is the longest parallel, while the poles are the shortest. Parallels are used to determine latitude, which is the measure of how far north or south a location is from the equator. Meridians Meridians are semi-circles that run from the North Pole to the South Pole. They are measured in degrees east or west of the Prime Meridian, which is the meridian that passes through Greenwich, England. The distance between two adjacent meridians is the same everywhere on Earth. The Prime Meridian is the longest meridian, while the 180° meridian is the shortest. Meridians are used to determine longitude, which is the measure of how far east or west a location is from the Prime Meridian.
Parallels are numbered north or south from the equator (starting at 0 degrees) towards the poles, with the equator at 0 degrees. Meridians are numbered east or west from the Prime Meridian (located at 0 degrees) towards the International Date Line, with the Prime Meridian at 0 degrees.
It's actually parallel to the parallels, since the parallels are by definition parallel to the equator.
The imaginary line is called the Prime Meridian.
Nothing is parallel to any meridian. The equator is a parallel of latitude, and is parallel to all the other parallels. This is a big part of the reason that, collectively, they are called 'parallels'.
The equator is the parallel of zero latitude.
The equator is the parallel of zero latitude.
