With the help of geometric intuition, the complex mathematical problems can be simplified and vivid, which can help to explore the solutions to problems and predict the results.Geometry visualization can help students to understand mathematics intuitively and play an important role in the whole mathematical learning process. In mathematics teaching, it is necessary to guide students to use drawing as a strategy to solve the problem.With appropriate graphics and intuitive models, it is beneficial to understand mathematics problems in depth, to broaden students ’thinking of solving problems, to help them find the solution to the problem and to improve students’ Modeling ability
