With the notion of number-shape combination,an interesting geometric problem is studied.When symmetric lens rotate a circle in the regular triangle,the solutions of the trajectory of its center and the area of planar region which the trajectory forms are obtained.

Key words: curve, equation, △-biangle, symmetric lens
