平面几何是几何学中的一个重要分支 ,它内容丰富、系统 ,是几何大厦的基底 .中学生最早接触真正的平面几何是在初二 ,由于平面几何注重推理论证 ,因此很多初中学生对此不能很快地适应 .其实 ,只要能够熟知概念 ,积极培养论证能力 ,平面几何也并不难学 .下面我们以小学和初一已? Plane geometry is an important branch in geometry. It is rich in content and system, and is the base of geometric building. The earliest contact between the students and the real plane geometry is in the 2nd year. Because the plane geometry pays attention to theoretical verification, many junior high school students cannot Adapt quickly. In fact, as long as you can understand the concept, actively develop the ability to demonstrate, plane geometry is not difficult to learn. Here we have to primary and junior have?
