From a mathematical point of view, this is a circle bisection method, which radiates to different positions with the center of the circle as the center. When the ray is the radius of a circle, a sector with equal radius can be obtained. On the bisection of the center of the circle, the arcs are also equal, so the areas of the sectors are also equal.

Call me then to solve the case ~ ~ ~
