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.
They're not. The imaginary lines of constant latitude are sometimes called "parallels"
of latitude.
The imaginary lines of constant longitude are sometimes called "meridians" of longitude.
The term "meridian" comes from the Latin meridies, meaning "midday"; the sun crosses a given meridian midway between the times of sunrise and sunset on that meridian. The same Latin stem gives rise to the terms a.m. (ante meridiem) and p.m. (post meridiem) used to disambiguate hours of the day when using the 12-hour clock.

A meridian is a geographical name for a great circle of the Earth passing through the Poles and any given point on the Earth's surface. Derived from the Latin word 'Meridianus'
Lines of longitudes are also called Meridians. These vertical lines are drawn from the North to South poles.The meridian through Greenwich, England, called the Prime Meridian, was set at zero degrees of longitude. The meridian on the opposite side of the earth from Greenwich is called the International Date Line (IDL), which is at roughly 180° longitude.
Meridians of longitude; parallels of latitude. Remember that meridians are all the same length (20,000 km) and that they meet at the poles. Parallels are, well, parallel, and are different lengths, the longest being the Equator.
-- Parallels are associated with latitudes. Meridians are associated with longitudes. -- Parallels are parallel, and no tweo parallels intersect. All meridians intersect all other meridians, at two places. -- Every point on a parallel has the same latitude. Every point on a meridian has the same longitude. -- Every parallel in the same hemisphere has a different length. Every meridian on Earth has the same length. -- Every parallel is a full circle. Every meridian is a semi-circle. -- Every parallel crosses all longitudes. Every meridian crosses all latitudes. -- The distance between two parallels is the same at every longitude. The distance between two meridians depends on the latitude where it's measured. -- To cross all parallels, you only have to travel 12,000 miles. To cross all meridians, you have to travel 24,000 miles.
That's going to depend on how you're holding your map or globe. -- If the north pole is at the top, then meridians to the left of the Prime Meridian mark west longitudes. -- If the south pole is at the top, then meridians to the left of the Prime one mark east longitudes. -- If the north and south poles are toward the sides of the map, then the Prime Meridian is a horizontal line between them, and there is nothing on Earth to the left or right of it.
-- The Prime Meridian, because it tells us where to start measuring all other longitudes from. -- 87.72135° west longitude, because it passes through my house.

longitudes or meridians
Name the two meridians east of the meridian on this map.

latitude longitudes are known as meridians
Longitudinal or longitude lines are the imaginary lines that are perpendicular to the equator. Latitudinal or latitude lines are parallel to the equator.

Meridians Meridians ;p
"Meridians" are the [straight] lines of Latitude (vertical, North-South lines) on a map, and Longitudes are the circular lines (horizontal, East-West) going around the world. So there can not be "Meridians of Longitude" that converge at a poll.
