True meridian through a point is the line in which a plane, passing that point and the north and south poles, intersects with surface of the earth. It thus, passes through the true north and south. the direction of true meridian through a point can be established by astronomical observations.

What is the purpose of the meridian arrow?
The meridian arrow is a feature on a theodolite or transit, used in surveying and engineering to orient the instrument with true north. By aligning the meridian arrow with the geographic or true north direction, surveyors can ensure accurate measurements and angles in their work.
If you fly west from the prime meridian do you lose hours?
If you fly west from the prime meridian, you will gain hours, not lose them. This is because you are crossing time zones in a westerly direction, where time is typically later than the time at the prime meridian.

True or false is the points east of the prime meridian are located between 0 degree and 180 degrees east longitude?
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.
What direction must the ship be sailing along a meridian?
To sail along a meridian, one must sail true north or true south. Meridians of longitude run N/S.

Is it true that there is an imaginary line that divides Earth into a Western Hemisphere and an Eastern Hemisphere?
The full circle formed by the Prime Meridian and the meridian of 180° longitude separates the eastern and western hemispheres.

Yes, that's an accurate statement. In fact, its independent clause is always true, regardless of the time.
What line longitude forms the other side of the Prime Meridian?
The opposite of the Prime Meridian -- 180° East (or West) Longitude -- is traditionally referred to as the International Date Line, though substantial portions of the line deviate from the true meridian in order to accommodate geopolitical boundaries (countries).

True or false is the points east of the prime meridian are located between 0 degree and 180 degrees east longitude?
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.
Is it true that the main line of longitude is called the greenwich meridian?
You might say that. The thing that makes it the "main" one is the fact that by international agreement, it's the meridian that's accepted as zero longitude. So whenever the longitude of a place is stated, you always know that the number means an angle measured from the "Greenwich Meridian".
