Answer 1

Răspuns:

4.

AG=(2/3)AB=2×12/3=8cm

GM=(1/3)AB=1×12/3=4cm

BG=(2/3)BN=2×15/3=10cm

GN=(1/3)BN=1×15/3=5cm

CG=(2/3)CP=2×18/3=12cm

GP=(1/3)CP=1×18/3=6cm

5.

a)GD=(1/3)MD-->4=(1/3)MD---->MD=12cm

MG=(2/3)MD=2×12/3=8cm

b)NG=(2/3)NE--->7=(2/3)NE--->NE=7×(3/2)=21/2=10,5cm

GE=(1/3)NE=(1/3)×(21/2)=21/6=3,5cm

c)PG=(2/3)PF--->9=(2/3)PF--->PF=9×(3/2)=27/2=13,5cm

GF=(1/3)PF=(1/3)×(27/2)=27/6=4,5cm
