Geometric terms of location

Geometric terms of location describe directions or positions relative to the shape of an object.

These terms are used in descriptions of engineering, physics, and other sciences, as well as ordinary day-to-day discourse.

For example, when referring to a drive shaft it is clear what is meant by axial or radial directions.

Or, in a free body diagram, one may similarly infer a sense of orientation by the forces or other vectors represented.

[citation needed] Common geometric terms of location are:
