Geometry definition
Geometry means "the measurement of the earth." Several decades of research in spatial navigation reveal that animals, including human toddlers, use geometric properties of their environment to guide their navigation to goal locations (e.g., Cheng & Newcombe, 2005; Gallistel, 1990; Thinus-Blanc, 1996). Because navigating creatures can ignore all features of the terrain over short distances when they are oriented, and instead find their way by using path integration to update their position, animals’ sensitivity to the geometry of the external environment is best revealed when they are disoriented. When an animal loses its own sense of direction, it must use external directional cues to reorient – to regain its heading and position with respect to locations in the environment. For example, when rats watch as food is buried in one corner of a rectangular arena and then are disoriented by covered rotation and placed back in the arena, they reorient themselves primarily according to the shape of the room, and therefore search with equal frequency at the correct corner and its diagonally opposite geometric twin (Cheng, 1986). The rats’ surprising failure spontaneously to use other available cues (such as distinctive odors or wall patterns) to break the room’s symmetry led to the formulation of the geometric module hypothesis. According to this hypothesis, disoriented animals regain their heading by establishing the congruence between the shape of the room as it is currently perceived and a representation of the room as it was previously experienced from a specific, known direction. While there is still an ongoing debate regarding whether these representations are egocentric and viewpoint-dependent (e.g., Wang & Spelke, 2002) or allocentric and viewpoint-independent (e.g., Burgess, 2006), many species of animals, from ants to chicks to human toddlers, have been shown to navigate spontaneously by the shape of the surrounding environment after they are disoriented (Brown, Spetch & Hurd, 2007; Cheng & Newcombe, 2005; Chiandetti & Vallortigara, 2008; Sovrano, Bisazza, & Vallortigara, 2002; Wystrach &
Geometry means the measures and properties of points, lines, and surfaces. In a GIS, geometry is used to represent the spatial component of geographic features.
Geometry means a building's shape or configuration, including setbacks of wall/column lines, reentrant corners, discontinuities in vertical and horizontal lateral force diaphragms, open storefront and building stiffness variations due to the distribution of resisting elements or the use of materials of differing properties within the same structural element, or other irregularities in plan or elevation.
