Is the international date line the longitude line that forms a great circle with the prime meridian?
Yes, it is.
Which line of longitude forms a great circle with the Prime meridian?
The 180th meridian or antimeridian is the meridian which is 180° east or west of the Prime Meridian with which it forms a great circle.
What line of longitude forms the other half of the prime meridian of the globe?
The Prime Meridian is complete as it appears on maps or globes. It forms a half-circle, and isn't missing anything. When joined with the Prime Meridian, the 180-degree meridian of longitude forms a complete great circle.
Why are lines of latitude and longitude called great circles?
They're not. A "great circle" is a circle drawn on a sphere that has its center at the center of the sphere. -- The only line of latitude that's a great circle is the equator. None of the others are. -- Each meridian of longitude is 1/2 of a great circle. In order to form a complete great circle, you have to glue it together with the other meridian of longitude that's directly opposite it on the other side of the globe. Like the Prime Meridian and 180° longitude, or 34° east longitude and 146° west longitude.
Are lines of longitude semicircles?
Paired lines of longitude (a line and its partner 180 degrees of longitude away) are great circles. A great circle is a circumference of the planet, whereas a small circle is a circular path (slice of a sphere) that does not circumscribe the sphere.
Is the international date line the longitude line that forms a great circle with the prime meridian?
Yes, it is.
What line of longitude forms a great big circle with the prime meridian?
180th Meridian
Which line of longitude forms a great circle with the Prime meridian?
The 180th meridian or antimeridian is the meridian which is 180° east or west of the Prime Meridian with which it forms a great circle.
Which line longitude forms the other half of the prime meridian?
The Prime Meridian is complete exactly as it appears on maps and globes. It forms a half-circle, and it isn't missing anything. When joined with the Prime Meridian, the 180-degree meridian of longitude forms a complete great circle.
What line of longitude joins with the prime meridian to make a complete circle?
The 180th meridian or antimeridian is the meridian which is 180° east or west of the Prime Meridian with which it forms a great circle.

What is meridan?
Meridian is a geological term. It can be used to describe a line of longitude or a celestial great circle.
Are latitude or longitude called great circles?
Only one line of latitude is a great circle ... the equator. Meridians of longitude are semi-great-circle, but we hardly ever use that term for longitude lines. "Great Circle" is a misnomer. It is actually the shortest straight line between two points on the surface of the spherical Earth. However, when plotted on a flat paper map (which is subject to considerable distortion) the path looks curved. But it's the MAP that is distorted; the path is straight.

What are the reference point for latitude and longitude?
The latitude and longitude references are lines, not points. The reference for latitude is the line that forms a circle and consists of all points with zero latitude. That line is called the "equator". The reference for longitude is the line that forms a semi-circle and consists of all points with zero longitude. That line is called the "Prime Meridian".
Is the Arctic Circle a latitude or longitude line?
it is a latitude
