爱因斯坦说:“西方现代科学的基础,是建立在两个伟大成就之上的,即古希腊哲学家发明的形式逻辑体系和可通过系统实验而发现的因果关系.”欧几里得开创了平面几何从公理到定理,再到推理的思维方式,现代任何一个学科几乎都有这种思维方式的影子.那么我们如何学好平面几何呢?一、初步感知用铅笔在纸上不连续地点画,可以出现点的形状.铅笔是学习平面几何的一个重要工具,因为铅笔画图便于修改.常用的工具还有橡皮、草稿纸(白纸)、笔记本、三角板(至少二 Einstein said: “The foundations of modern Western science are based on two great achievements, namely, the formal logic system invented by the ancient Greek philosophers and the causal relationship that can be found through systematic experiments.” "Euclid Have to create a plane geometry from axioms to the theorem, and then to reasoning mode of thinking, almost any modern discipline has the shadow of this way of thinking.So how do we learn plane geometry? First, the initial perception of a pencil on the paper is not continuous Pencils are an important tool for studying plane geometry because pencil drawings are easy to modify. Common tools include eraser, scratch paper (white paper), notebook, set square (at least two
