摘要
在“用解析方法建立两个三角形的亲似对应及投影理论的探讨”[1]一文基础上,研究两个三角形给定三对对应点的情况下,一个三角形不变,另一个三角形经过相似变换成后,与不变三角形构成亲似对应的规律,从而得出了独立亲似对应的一个定理(或称为独立亲似对应中值定理)。
Based on setting up relative similarity correspondence of fwo triangles with an analytical method and studying in projection theorem, in thispaper, the lawof that relative similarity correspondence of two triangles are constituted, one of with does not change in shape and area,and the other being change into a new one similarey, three pairs of correspondence points being known, therefor, the theorem in standing alone relative similarity correspondence is gotten (the theorem is also called standing alone relative similarity correspodencne middle numerical value theorem)
