| In triangle ACE and ABD, angle A is common, by condition, angle ABD = ACE, side AB = AC, then triangles ACE is equal to triangle ABD along the side and two adjacent angles, which was required to be proved.
Then AD = AE = 15 cm, BD = EC = 10 cm, AB = AC = 7 cm.
Answer: AD = 15 cm, BD = 10 cm, AB = 7 cm.
