Lines of longitude.
Vertical lines parallel to the prime meridian are lines of longitude.
The only lines that can run parallel to the Prime Meridian on any map are other meridians of longitude, and the only map on which they can be printed parallel to it is a Mercator Projection. They are not really parallel to the Prime Meridian.
The Prime Meridian is an imaginary line. All longitudes are reckoned as angles from it, and all parallels of latitude cross it.
The Equator is the imaginary line that runs east to west around the middle of the Earth, dividing it into the Northern and Southern Hemispheres.
