Tables, desks, the layout of cities on a map, boxes, construction blocks, paper, and the Dockland office building in Hamburg, Germany are all instances of parallelograms in everyday life. A parallelogram is a two-dimensional form with opposite sides and angles that are both equal in length and parallel to one another. Any object that has one of the three aforementioned shapes—rectangle, square, or rhombus—is a parallelogram.
An example of a parallelogram that is not also a square, rhombus, or rectangle is the Dockland office building in Hamburg, Germany. For Robert Vogel GmbH & Co., BRT Architekten finished it about 2006. The structure is situated between the Fischereihafen and the northern Elbe near the end of the Edgar-Engelhard-Kai. The structure, which resembles a ship with a cantilevering “prow” over the dock, is regarded as the city’s entrance.
