Question

rectilinear After admiring Frank Lloyd Wright's rectilinear buildings for years, the public was astonished by the giant spiral of the Guggenheim Museum. rectilinear*

Accepted Answer

(1) Moving in or forming a straight line. (2) Having many straight lines. Rectilinear patterns or constructions are those in which straight lines are strikingly obvious. In geometry, rectilinear usually means “perpendicular”; thus, a rectilinear polygon is a many-sided shape whose angles are all right angles (the footprints of most houses, with their extensions and garages, are good examples). But rectilinear is particularly used in physics. Rectilinear motion is motion in which the speed remains constant and the path is a straight line; and rectilinear rays, such as light rays, travel in a straight line.
