ΔABC ≈ ΔMNP =>TFa MN/AB=MP/AC=NP/BC <=>

<=> MN/8= 1/2 =NP/16
MN/8= 1/2 =>MN=8*1/2= 4
NP/16=1/2 =>NP=16*1/2= 8

<=> MN/8= 1/2 =NP/16
MN/8= 1/2 =>MN=8*1/2= 4
NP/16=1/2 =>NP=16*1/2= 8
In ΔABC avem:
AB = 8 cm
AC = 14 cm
BC = 16 cm
In ΔMNP avem:
MP = 7 cm
Raportul de asemanare = AC / MP = 14 / 7 = 2
=> MN = AB / 2 = 8 / 2 = 4 cm
=> NP = 16 / 2 = 8 cm
AB = 8 cm
AC = 14 cm
BC = 16 cm
In ΔMNP avem:
MP = 7 cm
Raportul de asemanare = AC / MP = 14 / 7 = 2
=> MN = AB / 2 = 8 / 2 = 4 cm
=> NP = 16 / 2 = 8 cm
