  skos:definition """En géométrie, le grand théorème de Poncelet (parfois appelé porisme de Poncelet) est un énoncé portant sur l'inscription des polygones dans les coniques : un polygone inscrit dans une conique et en circonscrivant une autre fait partie d'une famille infinie de polygones, eux-mêmes inscrits et circonscrits aux même coniques.

It is named after French engineer and mathematician Jean-Victor Poncelet, who wrote about it in 1822; however, the triangular case was discovered significantly earlier, in 1746 by William Chapple.
