Answer 1

Răspuns:

Explicație pas cu pas:

a) AD/BD = 6/12 = 1/2

AE/Ec = 5/10 = 1/2

Conform reciprocei t.Thales  DE||BC

b) AD/AB = 3/12 = 1/6

AE/AC = 4/16 = 1/6

Conform reciprocei t.asem.  DE||BC

c) AD = 25-5 = 20,  AE = 30-6 = 24

AD/BD = 20/5 = 4

AE/EC = 46/6 = 4

Conform reciprocei t.Thales  DE||BC
