Moving point problem is a class of junior high school geometry an important issue in the senior high school entrance examination questions are often involved in. Such problems due to examine the students movement changes in the thinking and methods to make the problem more abstract, more difficult However, if students are able to think and understand the graphics formed by some common moving points, the problem becomes concrete, the image and the method of solving the problem become vivid.
