AB congruent cu MN
BC congruent cu MN 

REzulta ca AB+BC=2MN
Determinati,folosind calculul vectorial,valoarea lui m pt care,in fiecare caz,punctele date sunt coliniare:
a)A(m,1),B(2,3),C(3,-1)
b)A(2,1)B(4,m)C(M,2)
c)A(0,2),B(2,m),C(m,6)
d)A(1,1)B(2,3)C93,m)
e)A(m,1)B(5,m),C(4,2)
f)A(m,m,-1),B(4,9),C(3,m) am nevoie de rezolvari complete e urgentva rog frumos am nevoie plizz
