Right Hand Rule(Terms of mathematics/geometry)
1.
Right handed cartesian coordinate systems are the standard coordinate systems for most applications and are used in most current CAD systems internally. Left handed cartesian coordinate systems follow the same rule, just using the left hand. They are most often used in surveillance, since they correlate well with flat projections of the longitude and latitude grids of orthogonal projections of the earth surface.
2.
It is to note here, that while the definition of right- or lefthandedness of screws and helixes is a mathematical rule, the orientation of polygons in computer graphics is only a convention, though one that is followed fairly consistently by most programs
