five sides of geometry that somehow became the world's most fortified piece of real estate
means A five-sided polygon — or, capitalized, the U.S. Department of Defense headquarters, named for its distinctive five-sided shape.
from From Greek 'pente' (five) plus 'gonia' (angle, corner) — literally 'five angles,' a cousin of words like 'polygon' and 'diagonal.' The same 'gonia' shows up wherever Greek geometry left its fingerprints. The military landmark borrowed the name straightforwardly in the 1940s when the building was raised, fittingly, with five sides.
