Régulières

Régulières is a term that can refer to several distinct concepts, primarily within the French language. In a general sense, it is the feminine plural form of the adjective "régulier," meaning regular, normal, or customary. This can apply to a wide range of contexts, such as regular meetings ("réunions régulières"), regular payments ("paiements réguliers"), or regular intervals ("intervalles réguliers").

In the context of mathematics, "régulières" is most commonly associated with geometric shapes. A regular polygon is a polygon that is both equilateral (all sides have the same length) and equiangular (all interior angles have the same measure). Examples include a regular triangle (equilateral triangle), a regular quadrilateral (square), and a regular pentagon. Similarly, a regular polyhedron is a polyhedron whose faces are all congruent regular polygons and whose solid angles are all congruent. The five Platonic solids are examples of regular polyhedra.

The term can also appear in other specialized fields. For instance, in military history, "les régulières" might refer to standing armies or regular troops as opposed to militia or irregular forces. In literature, it could describe poems or verses that adhere to a specific metrical pattern or rhyme scheme, as opposed to free verse. The precise meaning of "régulières" is thus dependent on the specific domain in which it is used.
