Problema are 2 solutii deoarece avem 2 variante
de amplasare a punctelor pe dreapta.
Varianta 1: B ∈ [AB]
A B C
|____.____.____.____|____|
[AB] = 4 cm
[AC] = 5 cm
⇒ [BC] = [AC] - [AB] = 5 - 4 = 1 cm
Varianta 2: A ∈ [BC]
B A C
|____.____.____.____|____.____.____.____.____|
[AB] = 4 cm
[AC] = 5 cm
⇒ [BC] = [AB] + [AC] = 4 + 5 = 9 cm
Varianta 3: C ∈ [AB] nu e posibila deoarece [AB] < [AC]
