Question

AB=8cm BN=3cm Stiind ca M si N sunt mijloacele segmentelor [AB] Rrespectiv [BC] calculati AM, MN si AC

Answer 1

AM=AB:2=4cm
MN=MB+BN=4+3=7cm
AC=AB+BC=8+6=14cm

Answer 2

M mijlocul [AB]
AM = MB = AB/2
AM= MB = 8 cm :2
AM= MB= 4 cm.

N mijlocul [ BC]
AB= 8 cm
BC = BN ×2
BC= 3 cm ×2
BC= 6 cm
AC = AB + BC
AC = 8 cm +6 cm
AC= 14 cm

MB= 4 cm
BN = 3 cm
MN = 4 cm +3 cm = 7 cm
