For all practical purposes, yes. But the earth is not a perfect oblate spheroid, although it is very close. If you want to get very picky, there may be technical differences in their lengths just because of the unevenness of the earth's surface in places. Meridians that cross only or mostly water would arguably be of the shortest possible length. Those crossing mountain ranges or otherwise quite varied terrain would be technically longer.

Are all meridians of equal length?
No
Why was it necessary to specify a particular meridan when determining the length of a meter?
I don't see the need for that - all meridians (for example, at sea level) should have the same length.
Which lines of longitude and latitude vary in length?
-- All meridians of longitude have the same length ... they all join the north and south poles. -- Each parallel of north latitude has the same length as the parallel at the equal south latitude, but no other one.
Why aren't all parallels equal in length like meridians are?
There's a simple answer: The earth is a sphere and the parallels are, well, parallel to each other. So obviously the ones closer to the poles are shorter than the ones closest to the Ecuator. As for the meridians all meet at one point ehich are the poles, so they are all the same length.
Are the lines of longitude the same distance apart at the equator as they are at the poles?
No. All of the meridians merge in a single point at the poles.

Lines of longitude called what?
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.
Does every meridian have the same length and the same beginning and end points?
No, not all meridians have the same length or the same beginning and end points. Meridians are imaginary lines on the Earth's surface that run from the North Pole to the South Pole. The prime meridian, which passes through Greenwich, England, is considered the starting point for measuring longitude.

Why are lines of longitude always the same length?
Lines of longitude are called meridians and converge at the poles. The length of a meridian is determined by the circumference of the Earth, making all lines of longitude the same length. This is because the Earth's shape is an oblate spheroid, with meridians meeting at the poles and being widest at the equator.
Differences between parallels and meridians?
Parallels are lines of latitude that run parallel to the equator, while meridians are lines of longitude that run from the North Pole to the South Pole. Parallels measure distance north or south of the equator, while meridians measure distance east or west of the Prime Meridian. Together, parallels and meridians form a grid system used to locate points on the Earth's surface.
Why are longitudes called meridians of longitudes?
as all the places on the same longitude have their noon at the same time
What are the longest latitude and longest longitude?
The longest parallel of latitude is the one defined as 'zero degrees', known as the "Equator". All meridians of longitude have the same length ... 1/2 of the earth's polar circumference.
Where do the meridians meet?
The meridians meet at the poles, which are the points on Earth's surface where the lines of longitude converge. At the North Pole, all lines of longitude meet, and the same is true for the South Pole.
Where do all meridians meed?
All meridians of longitude converge (meet) at the north and south poles.
