The distance of a point from a line is the length of the shortest line segment from the point to the line. The distance between two points is the length of a straight line segment that links them. A measurement of how far through space. Distance. This lesson describes the mathematical formula for determining distance and gives some examples. Distance. Definition of. Distance Formula in …

2 a (1) mathematics : an extent of area or an advance (see advance entry 2 sense 1) along a route measured in a straight line measure the distance between point A and point B the distance between the Earth and the Sun.

The distance between two points defined as the square root of the sum of the squares of the differences between the corresponding coordinates of the points; for example, in two-dimensional Euclidean geometry, the Euclidean distance between two points a = (a, a) and b = (b, b) is defined as: Distance is a numerical description of how far apart two objects are. (2) : an extent of space measured other than linearly within walking distance. See: Displacement (distance) Copyright © 2018 MathsIsFun.com. This will also be perpendicular to the line.
