Origin: A borrowing from French. Etymon: French rectangle.

Etymology: < Middle French rectangle (French rectangle ) right angle (1484; now obsolete), plane figure with four straight sides and four right angles (1556) < post-classical Latin rectangulus , adjective (see rectangle adj.). Compare post-classical Latin rectiangulum right-angled triangle (a636 in Isidore), rectangulum plane figure with four straight sides and four right angles (c1596 in a British source), Italian rettangolo plane figure with four straight sides and four right angles (1561).

1. A plane figure with four straight sides and four right angles, opposite sides being parallel and equal in length; esp. one in which adjacent sides are unequal, as contrasted with a square. Later also more generally: a thing having the shape of a rectangle.golden rectangle: see the first element.

Origin: Of multiple origins. Partly a borrowing from French. Partly a borrowing from Latin. Etymons: French rectangle; Latin rectangulus.

Etymology: < Middle French rectangle (c1400 in triangle rectangle ; French rectangle ) and its etymon post-classical Latin rectangulus (from 12th cent. in British sources), alteration of rectiangulus right-angled (6th cent.) < classical Latin rectus straight (see rect adj.) + angulus angle n.² Compare Italian rettangolo (a1472 as rettangulo ). Compare slightly earlier rectangle n., and also rectangular adj., rectangled adj.

Mathematics. Now rare or historical.

Containing one or more right angles; = right-angled adj. 1. Esp. in rectangle triangle. Cf. rectangled adj. 1.
