| By the property of the bisector of the angle of a triangle, the bisector divides the opposite side into segments proportional to the adjacent sides.
By the condition AB = BC = 6 cm.
Let the segment BE = X cm, then CE = (BC – X) = (6 – X) cm.
Then:
BE / AB = CE / CA.
X / 6 = (6 – X) / 8.
36 – 6 * X = 8 * X.
14 * X = 36.
X = 36/14 = 18/7 = 2 (4/7) cm.
BE = 2 (4/7) cm.
CE = 6 – 2 (4/7) = 24/7 = 3 (3/7) cm.
Answer: BE = 2 (4/7) cm, CE = 3 (3/7) cm.
