Abstract：In order to solve the shortcomings of traditional triangle recognition methods in certain triangle judgments, this paper uses the knowledge of spatial analytic geometry to describe triangles in set language, and designs a method to consider the whole problem in triangle recognition process from the perspective of geometric language. In the whole process, all the starting points and ideas are derived from the spatial position and quantity relationship. In this way, the intermediate feature factor and membership function are constructed, and the advantages and disadvantages of the method are identified in an intuitive way, so as to debug the most suitable membership function for the actual situation
