International Date Line
It's called the 180th meridian.
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.
The 180 degree line of longitude is called the 180th meridian or the antimieridian. This line is 180 degrees east or west of the Prime Meridian such that longitude at 180E and 180W is the same line. The International Date Line basically follows this line from the North and South poles..
Las Vegas is located at approximately 115 degrees west longitude. To find the degrees of longitude that separate it from the International Date Line at 180 degrees, you subtract 115 from 180, resulting in a difference of 65 degrees. Therefore, there are 65 degrees of longitude between Las Vegas and the International Date Line.
The major line of longitude located at 180 degrees longitude is the International Date Line.

180 degrees
No. 90 degrees longitude is not a major line of longitude. Only 0 and 180 degrees longitude, which are the Greenwich Meridian and the International Date Line respectively, are major lines of longitude.
The international date line
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.
They are called the lines of longitude. Lines of longitude range from 0 degrees on the prime meridian to 180 degrees.
Whether travelling to the West or to the East from the Prime Meridian (zero Longitude) the International Date Line is 180 degrees Longitude.
