Starting from the Prime Meridian and going either east or west, you'll cover 360
degrees of longitude before you find yourself back at the Prime Meridian again.
Half-way around a sphere corresponds to 180 degrees.
If you and your friend both start out from the Prime Meridian, and one of you
travels east around the globe and the other travels west around the globe,
you'll eventually meet each other. If you both travel exactly the same distance,
then you each cover 180 degrees of longitude, and you meet exactly on the
other side opposite the Prime Meridian, in the middle of the Pacific Ocean, at
180 degrees longitude, both east and west.
There are 180 degrees of longitude on each side of the Prime Meridian. This is because there are 360 degrees in a circle.
180 degrees in each direction.
Each of those lines is a meridian of longitude. They are 180 degrees apart in longitude,so together they form a complete circle around the Earth. That circle is the boundarybetween the eastern and western hemispheres.
The time meridian is each standard time zone roughly centered on a line of longitude exactly divisible by 15 degrees and the prime meridian is the starting point for the standard time zones an arbitrary longitude line.
Yes, all points east and west of the Prime Meridian are both between 0 and 180 degrees longitude because there are a total of 360 degrees of longitude on a globe divided into 180 degrees on each of the eastern and western hemispheres.
Technically Yes. Concerning longitude, all of the meridians come together at the poles, so each pole has every longitude, but by convention 0 degrees longitude is used to refer to the north or south poles. So for example, the North pole is typically referred to as at 90°N 0° W and likewise the South pole as 90°S 0° W.With respect to latitude, the north pole is located at 90 degrees north latitude, and the south pole at 90 degrees south latitude.
The longitude of every point on Earth, from the Prime Meridian out to halfway around the world in the westerly direction is labeled "west longitude". The longitude of every point on Earth from the Prime Meridian out to halfway around the world in the easterly direction is labeled "east longitude".

Yes. One of them is labeled "30° east" and the other is labeled "30° west".
The longitude of every point on Earth, from the Prime Meridian out to halfway around the world in the westerly direction is labeled "west longitude". The longitude of every point on Earth from the Prime Meridian out to halfway around the world in the easterly direction is labeled "east longitude".
The 'Longitude' of a place is. "Angular measurement" is correct, but there's no law that says that longitude absolutely must be described in degrees. Any other unit of angle could be just as effective, mathematically and cartographically, even if it's unconventional.
The halfway point between the Prime Meridian (0°) and the 180° line of longitude is the 90° line of longitude, also known as the International Date Line. This line is located in the Pacific Ocean and marks where each new day begins.
The 'lines' that appear east and west of the Prime Meridian are the other meridians of longitude. But they don't circle the Earth. Each meridian is a semi-circle that joins the north and south poles, and has the same longitude at every point on it.
The Prime Meridian and the meridian of 180° longitude combine to form a great circle on the Earth. Each of them alone is a semi-circle.
Each 'side' of the Prime Meridian comprises 180 degrees, for a total of 360 degrees all the way around the Earth just as you would expect. You're free to draw as few or as many 'lines' in any of those intervals as you feel are necessary.
