在几何学发展的历史长河中,许多经久不衰的几何名题,犹如一颗颗闪烁的明珠,璀璨夺目,光彩照人,推动着几何学乃至整个数学的发展.它们中有的从一发现就吸引着人们的关注,有的经过几代甚至几十代数学家的努力,得出许多耐人寻味、发人深 In the long history of the development of geometry, many of the enduring geometric names, like the twinkling pearl, dazzling, brilliant, and promote the development of geometry and the whole mathematics, some of them attracted from a discovery With people’s attention, and some generations or even dozens of generations of mathematicians efforts, come to many thought-provoking, hair deep
