-- The "Prime Meridian" marks zero longitude.
-- The "180th meridian" marks 180° longitude.
The International Dateline is either on or relatively near the 180th meridian
at any given latitude on it.
They are exactly half a world apart.
The meridian of 0° longitude, known as the 'Prime Meridian', is the line between
the north and south poles that passes through a certain point in a certain room
in a certain building just outside London.
The meridian of 180° longitude also joins the north and south poles, and passes
through the Pacific Ocean.
Each of these meridians is a semi-circle. When they're joined, they form a complete,
flat circle, with exactly half of the Earth's surface ... the eastern and western hemispheres ...
on each side of it.
That point is way out in the central Pacific Ocean. It happens to be the farthest
you can get from any point on the Prime Meridian.
Approximate distances from there to some points on land are:
Tarawa . . . . . 485 miles
Funafuti . . . . . 600 mi
Tokyo . . . . . . . 3,550 mi
Port Moresby. . 2,350 mi
Brisbane . . . . . 2,600 mi
Anchorage . . . 4,510 mi
Seattle . . . . . . 4,760 mi
San Francisco . 4,490 mi
San Diego .. . . 4,660 mi
Panama Canal . 6,930 mi
Lima . . . . . . . . 7,100 mi
Antarctica, nearest point . . . 5,030 mi.
Distances to points on the Prime Meridian:
0° lat, 0° lon (Intersection of Equator and Prime Meridian) . . . 12,439.9 miles
North or south pole (ends of the Prime Meridian) . . . .. . . . . . . . 6,219.9 miles

The line of constant zero longitude is the Prime Meridian.
The line of constant 180° longitude is the 180th meridian. The International
Dateline coincides with it for a large part of its length, but not for all of it.
0 = Greenwich Meridian
180 = International Date Line (with a few small exceptions)
The equator is the line made up of all points on earth with zero latitude and any longitude.
The maximum degree of latitude is 90 degrees north and south, so 180 degrees latitude does not exist. If you meant 180 degrees longitude, then the answer would be that the International Date Line, a major line of longitude, is located there.
Longitude and latitude are measured in terms of degrees, minutes and seconds. Longitude has 360 degrees, while latitude 180 degrees of latitude.
The prime meridian is a line at 0 degrees longitude.
-- The northern and southern hemispheres each have 90 degrees of latitude and 360 degrees of longitude. -- The eastern and western hemispheres each have 180 degrees of latitude and 180 degrees of longitude.
The International Date Line runs primarily along the 180 degree longitudinal line. The Equator runs along 0 degrees latitude. The lines intersect along in the middle of the Pacific Ocean (0 degrees North, 180 degrees West).

There are 180 of latitude too - 90 south and 90 North.
The International Date Line runs primarily along the 180 degree longitudinal line. The Equator runs along 0 degrees latitude. The lines intersect along in the middle of the Pacific Ocean (0 degrees North, 180 degrees West).
The South Pole is at 90 degrees S latitude. The North Pole is at 90 degrees N latitude. All lines of longitude converge at both poles. There are 180 degrees of latitude between the North and South Poles, and 90 degrees of latitude between each pole and the Equator.
The maximum degree of longitude is only 180.
