If d, i = 1, 2, . . . , n, are the cevians that section an internal angle of a triangle at n + 1 congruent angles, then , where b and c are the measurements of the sides that determine the sectioned angle and k, k, . . ., k are the measurements of the segments determined by the cevians on the side opposite to the sectioned angle.
