Free practice questions for Calculus 3 - Distance between Vectors. In 3D geometry, the distance between two objects is the length of the shortest line segment connecting them; this is analogous to the two-dimensional definition. The distance between two lines in \(\mathbb R^3\) is equal to the distance between parallel planes that contain these lines.. To find that distance first find the normal vector of those planes - it is the cross product of directional vectors of the given lines. Keywords: Math, shortest distance between two lines.
