假设点 是三角形 内的任意一点， 、 和 是 相对于三角形 三顶点的重心坐标，则在三角形 内存在一点 和 有相同的重心坐标，同时我们有：

結果 (英文) 1:

Assumption point is any point within the triangle, and are relative to the coordinates of the three vertices of a triangle, then there is a point in the triangle and has the same coordinates, and we have:

結果 (英文) 2:

Point is the assumption that an arbitrary point inside the triangle, and the coordinates of the center of gravity with respect to the three vertices of the triangle, the triangle has the same memory and the focus point coordinates, and we have:

結果 (英文) 3:

Suppose is any triangle point,, and is compared with the barycentric coordinates of three vertices of triangle, triangle is in memory at one point and the barycentric coordinates of the same, we also have:
