Why the distance between two parallels is always equal except at the poles?

On a flat surface, in plane geometry, two parallel lines never meet; they are perfectly aligned with each other, so that they neither approach nor diverge from each other, at any distance. Parallel lines can meet at the poles, but not in plane geometry; this happens in spherical geometry. If the lines are on a sphere, such as, for example, the lines of longitude that are used (in conjunction with lines of latitude) to specify locations on the planet Earth, parallel lines meet at the poles. On a large scale, these parallel lines look completely different from those of plane geometry, but on a small scale, these huge circles will look much like line segments of plane geometry. Over short distances, the spherical surface of the Earth appears to be flat.

How do inclined planes work Are they always fixed?
Inclined planes are simple machines whose use enables a trade-off between mass and distance. They need no be fixed except that it may be sensible to anchor them during use.
What is the ratio of magnitudes of distance and displacement?
There's no firm relationship between the magnitudes of distance and displacement, except that displacement can never be greater than distance. So if you're looking for a ratio, I guess (distance)/(displacement) = or > 1
What is the point at which a planet is at its smallest distance from the sun in its orbit?
All the planets orbit in a perfect circle, so they always stay the same distance from the sun, except Pluto, which is why it is now a "Dwarf Planet".
How convert meter to square meter?
you multiply the number by itself. this is called squaring. * * * * * Except that a metre is a measure of distance while a square metre is a measure of area. You cannot convert between an area and a distance.
Why is the distance formula not needed to find the distance between two points that lie on a horizontal or a vertical line?
It is used, except that, because one set of coordinates are the same, the formula collapses into a simpler form.

What is another name for a line of a latitude?
They are sometimes called parallels. They are parallel to the equator, zero degrees latitude, and parallel to each other. They are all circles, except for the poles which are points.A parallel is another name for a line of latitude because all lines of latitude are parallel to each other.Graticule .parallels

What are latitude lines known as?
They are known as parallels - a bit of a misnomer, really, because there are no parallel lines on the surface of a sphere: lines of latitude themselves are not lines, but circles, except for the equator.

What is the name of lines of latitude that are north of the equator?
Except for a very few specific ones, the lines don't have names. The lines that mark latitudes north of the equator are "parallels of north latitude".
When did China gain independent?
China has always been independent, except for the period of Mongol rule between 1260 and 1370.
