At zero degrees longitude. Only on one side, the other side is the international date line.
zero degrees is not an angle because there is degrees
Slope = zero. The line is horizontal, parallel to the x-axis.
The equator.
There is only one Greenwich Meridian (which I think is what you're asking about). It is the zero degrees line of longitude, so when a map location is given the longitude is given as being east or west of Greenwich. It position, going through Greenwich is partly historical and partly practical - opposite the meridian is the International Date Line, which for practical reasons is placed in the sea.
Whether travelling to the West or to the East from the Prime Meridian (zero Longitude) the International Date Line is 180 degrees Longitude.
At zero degrees longitude. Only on one side, the other side is the international date line.
0 degrees longitude = the Greenwich Meridian and international date line 0 degrees latitude = the Equator.
The Prime Meridian, which is at longitude ZERO degrees, and the International Date Line. The International Date Line is supposed to be at longitude 180 degrees, but it varies quite a distance for political reasons.
Latitude ranges:Zero to 90 degrees northZero to 90 degrees southLongitude ranges:Zero to 180 degrees eastZero to 180 degrees west
zero degrees is not an angle because there is degrees
The point where they cross is zero latitude / 180° longitude.
Zero degrees of latitude is the Equator.
If you meant to write "180 degrees west and 180 degrees east," then they form a complete circle around the Earth, making them antipodal points. If you meant both points as 180 degrees west, they are the same location on the opposite side of the Earth.
If two travellers 'A' and 'B' started from the Prime Meridian (zero longitude). 'A' travelled to the West, and ''B travelled to the East, they will meet on the other side of the World at 180 degrees longitude. Therefore, the biggest number is 180 degrees longitude. The International Date Line roughly follows the 180 degrees longitude north-south line on the Earth.
The distance is zero. The north pole is one end of the International Dateline. The south pole is the other end.
By definition, the UK lies across the Prime Meridian - the zero Longitude line. The International Date Line, is positioned mainly 180 degrees around the globe, running from pole to pole, but has a few wiggles in it to avoid some minor land masses.But of course it can not avoid the Antarctic land mass.
