Question

AP este mediana in TRIUNGHIUL ABC,P apartine (BC),Aabc=20 cm^2,AB=15cm,determinati d(P.AB)

Answer 1

AP mediana imparte triunghiul in 2 triunghiuri de arii egale
deci Aabp=Aabc/2=10
d(P,AB)=h
Aabp=AB*h/2
10=15*h/2
h=20/15=4/3

Answer 2

In triunghiul APB , d(P,AB)=h
Aapb=Aabc/2=20/2=10cm patrati
Aapb=h*AB/2
10=h*15/2 -> h=2*10/15=20/15=4/3 -> d(P,AB)=4/3 cm
Sper ca te-am ajutat :)
