I'm not exactly sure what you are asking, but the lines parallel to the equator are the tropics of cancer and Capricorn, and the lines perpendicular to the equator are the prime meridian (defined as zero degrees) and the 180th meridian. Together the 180th and the prime meridians make a type of equator going around the earth longitudinally (up and down). Prime Meridian goes through the Royal Greenwich Observatory in Greenwich, England. The 180th meridian is the line that the international date line generally follows.
The zero meridian used by satellite navigation systems (or GPS) is actually about 102 meters east of the actual prime meridian line in Greenwich, England. This zero meridian of the satellites is set to the actual center of the earth.

Lines of Latitude.
The 2 main lines of latitude other than, and parallel to, the Equator are: -
The Tropic of Cancer .. 23.5° North of the Equator
The Tropic of Capricorn .. 23.5° South of the Equator
Running from N to S are lines of Longitude.

The correct answer is the Greenwich Prime Meridian which runs pole to pole crossing over (actually not directly over, just close to) Greenwich, England.

There is also the axis of the earth which is the line through the two poles.

I don't think anyone else has mentioned them but there is also the Arctic circle, and obviously its counterpart the Antarctic circle, I should get the points for being different,surely?
