In plane geometry it is a straight line. If you want to know the shortest line between two points on a globe, it will be the intervening section or arc of the great circle route that connects the points. The great circle will be a circle that cuts the globe into exactly equal parts, like the equator.
between two point there is exactly one line between three points there is exactly one plane
an arc
is a segment of the line consisting of any two points and the part between
"Points" are never considered a line segment. Points are never anything else but points.But any two points 'determine' a line segment, because there's only one line segmentthat can be drawn between them.So if you have several points on a line, then any two of them determine a segmentof that line.
The question is curiously vague. Do the two lines exist in the same plane? If they do, then they must intersect somewhere -- unless they are parallel. For non-parallel lines, the distance between the two lines at the point of intersection is zero. For parallel lines, the shortest distance between them is the length of the line segment that is perpendicular to both. For intersecting lines, there is an infinite number of distances between the infinite number of pairs of points on the lines. But for any pair of points -- one point on line A and another on line B -- the shortest distance between them will still be a straight line. Given two lines in 3D (space) there are four possibilities # the lines are collinear (they overlap) # the lines intersect at one point # the lines are parallel # the lines are skew (not parallel and not intersecting) The question of "shortest distance" is only interesting in the skew case. Let's say p0 and p1 are points on the lines L0 and L1, respectively. Also d0 and d1 are the direction vectors of L0 and L1, respectively. The shortest distance is (p0 - p1) * , in which * is dot product, and is the normalized cross product. The point on L0 that is nearest to L1 is p0 + d0(((p1 - p0) * k) / (d0 * k)), in which k is d1 x d0 x d1.
The shortest distance between any two points is called displacement.
this is supposedly the shortest distance between any 2 points, however if you could bend the space between the two points and fold them together, well then they would be right beside each other
actually, there is, depending on your definition of polygon, and your definition of a line segment. A line segment is the shortest path btwn two points, right? So take a sphere and pick any two points on that sphere. The shortest path between them on the surface of the sphere would be a "curve" along the surface, but it's the shortest path between the points, so it technally is a line segment. Take two of these line segments that intersect at two points, and there is your two sided polygon!
The equator.
A line.
No. A line is the locus of all points located between any two points.
There are an infinite number of points between any two numbers on the real number line.
The distance between any two points on a number line is the absolute value of the difference of the coordinates.
No
The shortest distance between any 2 points. An ideal zero-width, infinitely long, perfectly straight curve (the term curve in mathematics includes "straight curves") containing an infinite number of points. In Euclidean geometry, exactly one line can be found that passes through any two points.A line in math is a straight line that goes forever on each side.

ehat describes how much a line rises or falls between any two on that line
