It is the length of the line segment that is perpendicular to the line and passes through the point. Midpoint is used in geometry to describe the point along a line that is equidistant from the end points of that line. Clamp 't' to the range 0 to 1. There are several formular examples of distance from point to line, but what I have is a vector starting position, a vector direction and a point in 3D space. The distance formula is derived from the Pythagorean theorem. A sketch of a way to calculate the distance from point $\color{red}{P}$ (in red) to the plane. In the context of determining parallelism in Euclidean geometry, a transversal is a line that intersects two other lines that may or not be parallel to each other. Vectors with Initial Points at The Origin. The absolute value sign is necessary since distance must be a positive value, and certain combinations of A, m , B, n and C can produce a negative number in the numerator.
