相似三角形的定义是相似三角形一节的基础概念,相似三角形的判定是相似三角形一节的重点内容之一.二者前承全等三角形及成比例线段,后续相似三角形的性质,所以我们必须努力学好相似三角形的定义和判定.现将其核心部分的学法建议分述如下,供大家学习时参考.
The definition of similar triangles is the basic concept of the similar triangles section. The determination of similar triangles is one of the key elements of the similar triangles section. Both of them are preceded by equal triangles and proportioned line segments, and follow similar nature of triangles, so we must work hard. Learn the definition and judgment of similar triangles. Now we will describe the learning methods of the core part as follows for your reference.
