Parallel lines are the same distance apart for all points along the line.
Parallel
the same distance
A circle or a sphere
Yes, in geography, all points along a parallel of latitude are indeed the same distance from the equator. This is because parallels are imaginary lines that run parallel to the equator, maintaining the same distance from it as they wrap around the Earth.
"1 pair" means "two". And "parallel" means the lines are on the same plane, but don't intersect. In other words, they are at the same distance at all points.
A globular sphere has all points at the same distance from an interiocenter point.
A curved surface on which all points are the same distance from the center is called a sphere.
The set of all points in space that are the same distance from a given point is called a sphere.
Parallel lines will never intersect. They will stay an equal distance apart at all points.
line
You're talking about meridians of longitude. It makes perfect sense that all the points that are the same distance east of something are going to all be on a north-south line. Just like all the points on the wall of your bedroom that are the same horizontal distance from the corner of the room are going to all be on the same vertical line.
