The distance (or perpendicular distance) from a point to a line is the shortest distance from a fixed point to any point on a fixed infinite line in Euclidean geometry. It is the length of the line segment which joins the point to the line and is perpendicular to the line.
12 maj 2009 · In F#, the distance from the point c to the line segment between a and b is given by: let pointToLineSegmentDistance (a: Vector, b: Vector) (c: Vector) = let d = b - a let s = d.Length let lambda = (c - a) * d / s let p = (lambda |> max 0.0 |> min s) * d / s (a + p - c).Length The vector d points from a to b along the line segment.
The distance between a point \(P\) and a line \(L\) is the shortest distance between \(P\) and \(L\); it is the minimum length required to move from point \( P \) to a point on \( L \). In fact, this path of minimum length can be shown to be a line segment perpendicular to \( L \).
The distance between a point and a line, is defined as the shortest distance between a fixed point and any point on the line. It is the length of the line segment that is perpendicular to the line and passes through the point.
Shows how to find the perpendicular distance from a point to a line, and a proof of the formula.

The distance from a point to a line is the shortest distance between them - the length of a perpendicular line segment from the line to the point. Try this Adjust the sliders to change the line equation and drag the point C. Note the distance from the point to the line.
