CD = 5 cm
DC = 10 cm
AD = 20 cm
AE = 25 cm
BD = 8 cm
BE = 18 cm
CE = 15 cm.
___________
AB = AE - BE = 25 cm - 18 cm = 7 cm
AC = AE - CE = 25 cm - 15 cm = 10 cm
BC = AC - AB = 10 cm - 7 cm = 3 cm
BD = BC + CD = 3 cm + 10 cm = 13 cm
AD = AC + CD = 10cm + 10 cm = 20 cm
AE = AC + CE = 10 cm + 15 cm = 25 cm
BE = AE - AB = 25 cm - 7 cm = 18 cm
DE = CE - CD = 15 cm - 10 cm = 5 cm
