The moving point problem-solving skill of geometric figures is a method to solve complex mathematical problems. The basic idea of this method is to grasp the form and process of motion change and think about the relationship between geometric elements and the available quantities in the initial state of motion. First, determine the position of the moving point in the specific figure, and draw a figure that conforms to the meaning of the question-turning motion into static. According to the known conditions, the algebraic expression with T is used to express the moving distance of the moving point and the conditions needed to solve the problem. According to the requirements, the equivalence relationship is found by using the properties or mutual relations of special graphs, and the equations for solving the moving point problem are listed.
