Every point on a meridian has the same longitude.

They are both imaginary lines on the Earth's surface. To say that they are both circles... an answer you might have been expecting ... would be a wholly inappropriate statement, because a meridian of longitude is only a semicircle.
-- Longitude is the angle east or west between a point on the Earth's surface and the Prime Meridian. -- Latitude is the angle north or south between a point and the equator. -- A meridian is an imaginary line between the north and south poles and through all the points on Earth that have the same one single longitude.

A Meridian or Meridian Line is an imaginary line drawn between two points. In geography these two points are an imaginary arc on the earths surface from the North to the South Poles. In astronomy it is an imaginary circle in a perpendicular plane to those planes of the celestial equator and horizon.
Every point on a meridian has the same longitude.
the prime meridian
It is an imaginary line in the surface of the earth which is opposite of the prime meridian which offsets the date as one travels east or west.
It's either Latitude & Longitude or the Prime Meridian
Both are imaginary lines on the Earth's surface related to navigation and cartography. Aside from that, very little if anything.
They are both imaginary lines on the Earth's surface. To say that they are both circles... an answer you might have been expecting ... would be a wholly inappropriate statement, because a meridian of longitude is only a semicircle.
The letters 'deaiimnr' spell meridian, a word for an imaginary circle on the earth's surface passing through the north and south poles.
There are two lines that both terminate at the poles: the International Date Line and the Prime Meridian.
-- Longitude is the angle east or west between a point on the Earth's surface and the Prime Meridian. -- Latitude is the angle north or south between a point and the equator. -- A meridian is an imaginary line between the north and south poles and through all the points on Earth that have the same one single longitude.
-- The longitude of the Prime Meridian is zero. -- Every point on the Prime Meridian has a different latitude. -- For every possible latitude, there is a point on the Prime Meridian.
