Find the distance from the point $S(2,2,1)$ to the line $x=2+t,y=2+t,z=2+t$. How can I find the distance of a point in $3D$ to a line?
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.
27 maj 2015 · You need to find the point on the line that is closest to your point--which occurs when the line joining the point to your line is perpendicular to your line.
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.
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.
