本文主要介绍中学几何基本型中的三种类型——“对角互补型”、“角平分线型”和“8”字型,所谓对角互补型,即为一组对角互补的四边形.角平分线型即为垂、折、腰、合、比五个转化模型.8字型可分为8字全等型和8字相似型.我们探讨此三种类型的构造及转化方法.
This article mainly introduces the three types of geometric basic model in high school - “diagonal complement ”, “angle bisector ” and “8 ” font, the so-called diagonal complement, that is a group Diagonally complementary quadrilateral.Diagonal bisector type is hanging, folding, waist, closing, than the five conversion model.8 font can be divided into 8-word and 8-word type of similar type.We explore these three types of Structure and transformation methods.
