Distance between two points is the length of the shortest connection from to
The distance , also the distance or the distance between two points, is the length of the shortest connection between these points.
In Euclidean space this is the length of the straight line between the two points. The distance between two geometric objects is the length of the shortest connecting line between the two objects, i.e. the distance between the two closest points. If the points of two objects that are closest to one another are not considered, this is stated explicitly or results from the relationship, such as the distance between the geometric centers or the centers of gravity.
The metric is the part of math that deals with measuring distance.
The interval , the distance , the distance between two values of a quantity or between two points in time is determined by forming the absolute value of their difference , that is, by subtracting them from one another and forming the absolute value from the result. The measured distance is independent of the selected reference point of the coordinate system , but not of its scaling ( see also scale factor ).
