Orientation (geometry)

Standard anatomical terms of location deal unambiguously with the anatomy of animals, including humans.

Anisotropy /ˌænaɪˈsɒtrəpi/ is the property of being directionally dependent, which implies different properties in different directions, as opposed to isotropy.

Isotropy is uniformity in all orientations; it is derived from the Greek isos (ἴσος, "equal") and tropos (τρόπος, "way").

In mathematics, orientation is a geometric notion that in two dimensions allows one to say when a cycle goes around clockwise or counterclockwise, and in three dimensions when a figure is left-handed or right-handed.

The four cardinal directions or cardinal points are the directions of north, east, south, and west, commonly denoted by their initials: N, E, S, W.

The North Magnetic Pole is the point on the surface of Earth's Northern Hemisphere at which the planet's magnetic field points vertically downwards (in other words, if a magnetic compass needle is allowed to rotate about a horizontal axis, it will point straight down).

A rotation is a circular movement of an object around a center (or point) of rotation .

The galactic coordinate system is a celestial coordinate system in spherical coordinates, with the Sun as its center, the primary direction aligned with the approximate center of the Milky Way galaxy, and the fundamental plane approximately in the galactic plane.

In geometry, various formalisms exist to express a rotation in three dimensions as a mathematical transformation.

A galactic quadrant, or quadrant of the Galaxy, refers to one of four circular sectors in the division of the Milky Way Galaxy.

Dexter and sinister are terms used in heraldry to refer to specific locations in an escutcheon bearing a coat of arms, and to the other elements of an achievement.

Sinistral and dextral, in some scientific fields, are the two types of chirality (“handedness”) or relative direction.

The history of the compass extends back for more than 2000 years.
