The Prime Meridian is complete in and of itself, with nothing missing.
It's only a semi-circle, however, which may, understandably, leave some with an
uncomfortable feeling of virtual incompletitude.
Those who feel that there's something inherently unsatisfying about a semi-circle
may join the Prime Meridian with the meridian of longitude at 180°, and thereby
arrive at a partnership that forms a true, complete, great circle on the Earth.
The Prime Meridian is complete as it appears on maps or globes. It forms a half-circle, and isn't missing anything. When joined with the Prime Meridian, the 180-degree meridian of longitude forms a complete great circle.
The longitude of every point on the Prime Meridian is Zero.
The Prime Meridian is a line of longitude, and it sits at 0 degrees longitude.

The Prime Meridian is complete exactly as it appears on maps and globes. It forms a half-circle, and it isn't missing anything. When joined with the Prime Meridian, the 180-degree meridian of longitude forms a complete great circle.
180th Meridian
The Prime Meridian is complete as it appears on maps or globes. It forms a half-circle, and isn't missing anything. When joined with the Prime Meridian, the 180-degree meridian of longitude forms a complete great circle.
The Prime Meridian is complete just the way it's drawn on maps or globes. It's not missing anything. When the Prime Meridian is joined with the 180° meridian of longitude, the combination forms a single, complete great-circle.
The longitude of every point on the Prime Meridian is Zero.
The Prime Meridian is a line of longitude, and it sits at 0 degrees longitude.
The 180th meridian or antimeridian is the meridian which is 180° east or west of the Prime Meridian with which it forms a great circle.

The opposite of the Prime Meridian -- 180° East (or West) Longitude -- is traditionally referred to as the International Date Line, though substantial portions of the line deviate from the true meridian in order to accommodate geopolitical boundaries (countries).
