Shows how to find the perpendicular distance from a point to a line, and a proof of the formula.
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 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.
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 \( L \).
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.
In this explainer, we will learn how to find the perpendicular distance between a point and a straight line or between two parallel lines on the coordinate plane using the formula. By using the Pythagorean theorem, we can find a formula for the distance between any two points in the plane.
Distance from a point to a line — is equal to length of the perpendicular distance from the point to the line. Distance from a point to a line in space formula.
