The distance between the center of sphere S and the center of sphere T is 19.
because they never intersect
I-10 and I-45 intersect in Houston.
Parallel lines never intersect and remain equal distance from each other but perpendicular lines intersect at right angles
Parallel lines remain the same distance apart and never intersect each other whereas other types of lines intersect each other at some point.
Since they share a border the distance in between them is 0, but the straight line distance from the eastern border of New Mexico to the western border of Arizona it is 619.96 miles, respectively.....
A map scale.
The distance between Miami Florida to South pole is 12,855 km. On the other hand, the distance to North Pole and Equator is 7,149 km and 2,853 km respectively.
It is a chart giving the distance between places. You have a table with a list of places forming row and columns. The cell where the two intersect gives the distance between the two. Since the distance from A to B is the same as the distance from B to A, only half the square needs to be filled in - hence the triangle.
Declination (positive and negative respectively) is the angular distance between north and south of the Celestial Equator.
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.
Two lines in a plane are parallel if they do not intersect, meaning they maintain a constant distance between each other and will never meet.
They are mutually perpendicular. However, they need not intersect: if they are in different planes, they will not intersect.
