The positional relationship in solid geometry refers to: straight line and straight line, straight line and plane, plane and plane are parallel and vertical;

The angle formed by lines (intersecting straight lines, non-planar straight lines),

The angle formed by the line and the surface;

The distance from a point to a straight line.

The positional relationship in a vector refers to the translation of the vector,

Parallel (* * * line), vertical,

The included angle of the vector.

This paper mainly discusses the positional relationship of analytic geometry:

Translation, rotation, folding of curves, etc.
