Which meridians paired with their opposite meridians are great circles?

Any meridian, paired with the meridian exactly 180 degrees different in longitude,
comprise a great circle.
If the two meridians are not exactly 180 degrees apart in longitude, then they're
not in the same plane, and they don't form a circle at all.
No two meridians of longitude can combine to form a small circle.
All parallels of latitude, except the equator, are small circles. The equator is the only
great one.

Are meridians halves of small circle?
-- Each meridian joins the north and south poles, making it a semi-circle. -- The center of the circle of which it is a semi is at the center of the Earth, making it a 'great' one. Among parallels of latitude, only the equator is a great circle.
When you move away from the equator where do meridians go?
Meridians converge at the poles and intersect the equator at 90 degrees. They are all great circle lines called lines of longitude. The equator is a line of latitude and the only line of latitude that is a great circle line. As you move away from the equator the lines of latitude describe smaller and smaller circles round the planet as you approach the poles.
Why all meridians of longitude are semi-great-circles?
-- Each meridian joins the north and south poles, making it a semi-circle. -- The center of the circle of which it is a semi is at the center of the Earth, making it a 'great' one. Among parallels of latitude, only the equator is a great circle.
What the another name for a line of longitude?
A line of longitude may also be known as a meridian.Meridians (lines of Longitude) are great circles that go round the Earth through the North and South Poles. So they represent one-half of a polar circumference of the planet.The Prime Meridian runs through England (Greenwich) and is 0 degrees longitude.
How to draw great circles and small circles drawn?
use a compass
A circle formed by two meridians directly across from each other on opposite sides of the globe is called what?
The Great Circle

Name the latitude that is truly a great circle?
The equator is the only parallel of latitude that's a great circle.In fact, it's the only locus of any constant coordinate that's a great circle,since the meridians of longitude are all semi-circles.

Why are longitudes called as meridians?
Why are longitude lines called meridians? In a geographical sense, meridians are great circles that are not parallel to each other but instead intersect each other at the north and south poles. This as opposed to paralles of latitude which are not great circles, except for the equator, and do not intercest each other.
Is the Tropic of Cancer a great circle?
No; neither of the tropics is a great circle. The only line of latitude that is a great circle is the equator. The arctic and antarctic circles are not great circles, either.
Why diametrically opposite lines of longitude and equator are called great circles?
A 'great circle' is any circle on the surface of a sphere that has its center at the center of the sphere. The equator is the only parallel of latitude that's a great circle. Every meridian of constant longitude is a semi-circle, and together with the one directly opposite it, they form a great circle. The shortest distance between two points on a sphere is the piece of the great circle through them.
Why are lines of longitude called great circles?
Because they make big circles around the Earth.
How many great circles are there on a sphere?
There are an infinite number. If you draw two great circles, no matter how close together they are, I can always draw a great circle ... or 2 or 3 or 10 ... between them.
