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.
Shows how to find the perpendicular distance from a point to a line, and a proof of the formula.
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.
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$(PQ) = d$.
To nd the distance of a point P to a line l we always consider the perpendicular distance from the point to the line. What does "perpendicular" distance mean? If we draw a line through the point P that intersects our line l at some other point Q, say, the distance from P to Q, PQ, is the "perpendicular" distance from the point P to l. This is ...
Learn how to find the perpendicular distance of a point from a line easily with a formula. For the formula to work, the line must be written in the general form.
The equation of a plane perpendicular to the line is $$x+y+z=a.$$ If this plane passes through $(2,2,1)$ then $a=5$. So the plane $x+y+z=5$ intersects the line when $$3t+6=5$$ so $t=-\frac{1}{3}$ and now you just need the distance between $S$ and $(\frac{5}{3},\frac{5}{3}, \frac{5}{3})$.
