Abstract
In this paper,we discuss category about planar central configuration of four-body problems by using algebra method,and draw some new conclusions:for the positive mass points,the central configuration of parallelogram must be rhombus or square;for the arbitrary none-zero mass points,parallelogram is the central configuration if it satisfies θ∈(0.97578,0.97579).
