In this paper, the precision characteristics of angle measurement intersection and measurement intersection are analyzed. The accuracy of the measurement of the angle measurement by the triangle figure is analyzed through the precise deduction of the precision of the corner intersection and the single triangle measurement. Through the calculation and verification of the typical graphs, it is concluded that the corner measurement has the advantages of precision complementarity. Therefore, it is suggested that the limitations of the graph [1, 2] for the corner combination network should be properly relaxed. This article provides a theoretical basis for the revision of the relevant norms in the future, and has reference value for the accuracy estimation of the corner net
