1. Geometry a plane figure consisting of four points connected by four lines. In a complete quadrangle, six lines connect all pairs of points
2. a rectangular courtyard, esp one having buildings on all four sides
3. the building surrounding such a courtyard

A rectangular courtyard or grassy area enclosed by buildings, most often used in conjunction with academic or civic building groupings.

[′kwä‚draŋ·gəl]
(civil engineering)
A four-cornered, four-sided courtyard, usually surrounded by buildings.
The buildings surrounding such a courtyard.
A four-cornered, four-sided building.
(mapping)
A four-sided tract of land, defined by parallels of latitude and meridians of longitude, used as an area unit in systematic mapping.
(mathematics)
A geometric figure bounded by four straight-line segments called sides, each of which intersects each of two adjacent sides in points called vertices, but fails to intersect the opposite sides. Also known as quadrilateral.

The most fruitful way to construct finite generalized quadrangles is through a now standard group coset geometry construction, in which a group E provided with certain sets of subgroups [epsilon] = {[E.sub.i] | i [member of] I} and [[epsilon].sup.*] = {[E.sup.*.sub.i] | i [member of] I}, I an index set, and satisfying some strong intersection properties, is used to represent a generalized quadrangle.
In the long literature of generalized quadrangles, it has appeared that one special type of EGQ plays a central role.

We describe it for generalized quadrangles. Let A be an apartment of a GQ [GAMMA].
The quasi-architectural articulation of negative space beginning to develop in Stanchion is clearest in Quadrangle, a large and lanky freestanding sculpture that filled the north gallery.
MacCormac Jamieson & Prichard have much experience of building for Oxford and Cambridge colleges and in the early '90s the office was chosen to design the Garden Quadrangle, a reinterpretation for the late twentieth century of traditional student accommodation set round a raised secret garden over an auditorium and dining hall (AR October 1994).
For this map, an overlay of the state with 15-minute quadrangles was used.
It should be pointed out that Thompson (2000a, b) correlates the Matthews Landing Member of the Porters Creek into the adjoining Camp Hill and Whittentown Quadrangles. The brief description in the map legend indicates a lithology consisting of interbedded to interlaminated, pale yellow sand with common siderite concretions and nodules.
With their tightly ordered social and physical structures, colleges were a reaction against the often ill-disciplined and undifferentiated character of early schooling, yet the humanly-scaled collegiate network of cloisters and quadrangles has became an enduring template for educational buildings of all kinds, from kindergartens to universities.
Located at Seattle University, a private Jesuit college of approximately 6000 students, the building is carefully positioned to define four new quadrangles in a developing area of this urban campus.
