Quadrilateral
In geometry a quadrilateral is a four-sided polygon, having four edges (sides) and four corners (vertices). The word is derived from the Latin words quadri, a variant of four, and latus, meaning "side". It is also called a tetragon, derived from greek "tetra" meaning "four" and "gon" meaning "corner" or "angle", in analogy to other polygons (e.g. pentagon). Since "gon" means "angle", it is analogously called a quadrangle, or 4-angle. A quadrilateral with vertices A {\displaystyle A} , B {\displaystyle B} , C {\displaystyle C} and D {\displaystyle D} is sometimes denoted as ◻ A B C D {\displaystyle \square ABCD} .Quadrilaterals are either simple (not self-intersecting), or complex (self-intersecting, or crossed). Simple quadrilaterals are either convex or concave. The interior angles of a simple (and planar) quadrilateral ABCD add up to 360 degrees of arc, that is ∠ A + ∠ B + ∠ C + ∠ D = 360 ∘ . {\displaystyle \angle A+\angle B+\angle C+\angle D=360^{\circ }.} This is a special case of the n-gon interior angle sum formula: S = (n − 2) × 180°.All non-self-crossing quadrilaterals tile the plane, by repeated rotation around the midpoints of their edges.

quadrilateral
A quadrilateral is a polygon with four sides (or edges) and four vertices or corners. The sum of its interior angles is always 360 degrees. Some specific types of quadrilaterals include rectangles, squares, parallelograms, trapezoids, and rhombuses.

having four sides, and consequently four angles; quadrangular
Quadrilateralnoun

Quadrilateral
In Euclidean plane geometry, a quadrilateral is a polygon with four sides and four vertices or corners. Sometimes, the term quadrangle is used, by analogy with triangle, and sometimes tetragon for consistency with pentagon, hexagon and so on. The origin of the word "quadrilateral" is the two Latin words quadri, a variant of four, and latus, meaning "side." Quadrilaterals are simple or complex, also called crossed. Simple quadrilaterals are either convex or concave. The interior angles of a simple quadrilateral ABCD add up to 360 degrees of arc, that is This is a special case of the n-gon interior angle sum formula × 180°. In a crossed quadrilateral, the four interior angles on either side of the crossing add up to 720°. All convex quadrilaterals tile the plane by repeated rotation around the midpoints of their edges.
Chambers 20th Century Dictionary
Quadrilateral
kwod-ri-lat′ėr-al, adj. having four sides.—n. (geom.) a plane figure having four sides: the four fortresses—Mantua, Verona, Peschiera, and Legnago—which form the points of a quadrilateral.—n. Quadrilat′eralness. [L. quadrilaterus—quatuor, four, latus, lateris, a side.]
Military Dictionary and Gazetteer
quadrilateral
In military language, an expression designating a combination of four fortresses, not necessarily connected together, but mutually supporting each other; and from the fact that if one be attacked, the garrisons of the others, unless carefully observed, will harass the besiegers, rendering it necessary that a very large army should be employed to turn the combined position. As a remarkable instance, and a very powerful one, may be cited the celebrated quadrilateral in Venetia, comprising the four strong posts of Mantua, Verona, Peschiera, and Legnago. These form a sort of outwork to the bastion which the southern mountains of the Tyrol constitute, and divide the north plain of the Po into two sections by a most powerful barrier. Napoleon III., in 1859, even after the victories of Magenta and Solferino, hesitated to attack this quadrilateral.
Entomology
Quadrilateral
four-sided: formed or bounded by four lines: in Odonata, a space on the wings of Zygoptera bounded by the lower sector of arculus, the sub-median vein, a cross-vein between these two, and the lower part of arculus.
