The Prime Meridian is the imaginary line defined as zero longitude. It joins the

north and south poles and passes through England, Spain, France, Mali,

Burkina Faso, Togo, Ghana, and Antarctica. On its way through England, it

crosses a certain mark on the floor of a certain room at the Royal Observatory

in Greenwich, outside London.

The meridian of 180° longitude is exactly opposite the Prime Meridian and

together, they form a complete circle. That meridian also joins the north and

south pole, and passes through the Pacific Ocean for most of its length.

The International Dateline roughly follows the meridian of 180° longitude, but

departs from it with zigs and zags in several places, in order to avoid splitting

any single state, country, or island group into two different calendar dates.

What line of longitude would be 180 degrees away from the prime meridian?

The 180th meridian or antimeridian is the meridian which is 180° east or west of the Prime Meridian ... It is common to both east longitude and west longitude. It runs through the Pacific Ocean, and was the nominal guideline for the position of the International Dateline, although the dateline itself had to depart from the antimeridian in several places.
