用模型法证明非欧几何的定理

Prove the Theorems of Non Euclidean Geometry with Mathematical Model

提供一种用模型法证明非欧几何定理的证明方法 ,在证明中可以使用欧氏几何的定理 。

wA mathematical model so called “Poincaré Model” is introduced to solve these problems by using the theorems of Euclidean geometry stead of Non Euclidean geometry. It makes students understand Non Euclidean geometry more easily and more deeply.
