构造三角形、圆、函数等几何图形解方程、证明不等式、证明恒等式等代数问题,充分利用几何直观性使代数问题变得直观、简洁.在数学解题中用构造法解题不仅使学生能直观地把握代数问题,而且有利于学生的数形结合思想的培养.
Construct the equations of geometry such as triangles, circles and functions, prove the inequality, prove the algebraic problems such as identities, and make full use of the geometric intuition to make the algebraic problems intuitive and concise.Using tectonic method to solve problems in mathematical problems not only make the students intuitive Grasp algebra problems, but also conducive to the students with the combination of the number of ideas.
