七年级(即初一)学生,由学习代数转到学习平面几何,即由学习数与式转到学习形,一般说来,学习难度增加了,常会感到难以入手.因此,学好几何起始知识,加快入门是学好整个几何的关键.这里,向同学们介绍一些几何入门的尝试方法,供大家参
In the seventh grade (first grade) students, learning algebra shifts to learning plane geometry. That is to say, learning numbers and formulas are transferred to learning shapes. In general, the difficulty of learning increases, and you often feel that it is difficult to get started. Therefore, learn the geometric starting knowledge. Accelerating entry is the key to learning the whole geometry. Here, introduce students to some of the geometrical starting methods for everyone to participate in
