5 dni temu · Solved examples to find the perpendicular distance of a given point from a given straight line: 1. Find the perpendicular distance between the line 4x - y = 5 and the point (2, - 1). Solution: The equation of the given straight line is 4x - y = 5 or, 4x - y - 5 = 0
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$(PQ) = d$.
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 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 \( L \).
