Desargues定理——几何学中美的鉴赏

Desarguse Theorem—Esthetical Appreciation in the Geometry

Desargues定理是射影几何中点线结合的重要定理,也是平面射影几何的基础之一。本文根据定理的构形,利用对偶原理,揭示了该定理所体现的图形之美以及应用之美。

Desargues theorem is one of the most important theorem associating point and line,and one of important background in pro- jective geometry.In this paper,we reveal some esthetical views of the theorem from graph and application.
