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.

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'renot 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 onlygreat one.
What is the measurement of east and west position on the globe?
Latitude is measured north or south of the equator. Longitude is measured east or west of Greenwich. You can remember that because Longitude circles are always long.
What is the latitude and longitude for equator?
The equator is a latitude line, so it has no specific longitude. The equator is at 0o north or south. There are many points on the equator, so every point on the equator has a different longitude.
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.
What tattoo would you get for crossing the prime meridian?
I don't think you mean the Prime Meridian. I think you mean the Equator, latitude not longitude. King Neptune is, I suspect, what you refer to. The Prime meridian is 0 degrees longitude, the Greenwich Meridian. the Equator is 0 degrees latitude & circles the Earth horizontally.
Why are the equator and all lines of longitude called great circles?
The equator and all lines of longitude are called great circles because the represent the circumference of the earth. The other latitude lines along the globe are smaller then the actually circumference.
Which meridians paired with their opposite meridians are great circles?

What is the latitude and longitude for equator?
The equator is a latitude line, so it has no specific longitude. The equator is at 0o north or south. There are many points on the equator, so every point on the equator has a different longitude.
Which parallels are not circles?
a cylinder

Is the equator located at o longitude o latitude or 180 longitude?
The equator is 0° latitude.
What are the names of the longitude that pass through the equator if yes then why?
All lines of longitude pass through the Equator.
What longitudes begin just to the east of the prime meridian and continue eastward to 180 degrees longitude?
It is known as the Eastern Hemisphere, with lines of longitude easterly from the Prime Meridian (zero longitude) to the Datum Line of 180 degrees longitude. In the opposite direction from the Prime Meridian is the Western Hemisphere. To the north of the Equator is the Northern Hemisphere, and to the south of the Equator is the Southern Hemisphere.
What are 3 qualities of the lines of longitude?
-- they are semi-circles -- they are not parallel -- they join the north and south poles -- they are perpendicular to the equator -- the higher the latitude, the closer together any two longitudes are -- at the poles, all longitudes are the same point -- for every longitude west, there is an equal longitude east
What are is another name for the line of longitude besides equator?
'Lines' of longitude are called "meridians".The equator is not one of them.
