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.
The distance of a point from a line is the shortest distance between the line and the point. Learn how to derive the formula for the perpendicular distance of a point from a given line with help of solved examples.
Shows how to find the perpendicular distance from a point to a line, and a proof of the formula.
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.
Main principle: if we want to find distance from line to point, we simply project point onto the vector, perpendicular to line, and find lenght of this projection. Look at the picture : we need to find a distance between line1 and line2. To do it, select point $x$ on the line1 and find lenght of projection of vector $\bar{x}$ onto vector $\bar ...
Perpendicular Distance from Point to Line. The shortest distance between point and line is calculated by finding the length of the perpendicular drawn from the point to the line. Consider the line l: $Ax + By + C = 0$ and point $P(x₁, y₁)$. Note that PQ is the perpendicular from point P to line l. Let l$(PQ) = d$.
