“Moving point type ” a wide range of questions, questions about innovation, examination of student analysis, problem solving skills, including space concepts, application awareness, reasoning ability, etc., in recent years the exam questions hot and difficult. The so-called “moving point type problem ” refers to the problem of setting the graph in the presence of one or more moving point, they are moving in a line segment, ray or arc open-ended topics. Study triangle, quadrilateral, function images from the perspective of transformation and movement, through the classification and research of different situations of moving point motion, in the moving point of moving point view
