在解决一些数学问题时 ,有时需要把已知条件重新进行一番“构造制作”,以一种新型的“数学模型”出现 ,这样问题就变得直观、简明 ,使较难的问题得以顺利解决。这种方法称之为“构造法”。一、构造图形有些几何图形 ,如直角三角形、正三角形、正方形、矩形、圆等是我们非常熟悉
When solving some mathematics problems, sometimes it is necessary to re-construct the known conditions to “construct and build” and emerge with a new “mathematical model”. This problem becomes intuitive and concise, and the difficult problems can be resolved smoothly. . This method is called “construction method.” First, the construction of some geometric figures, such as right triangles, triangles, squares, rectangles, circles, etc. are very familiar to us
