Triunghiurile abc si a'b'c' au laturile: ab=3cm; ac=2,6 cm; bc=1,(3)cm; a'b'=5,2 cm; a'c'=6cm; b'c'=2,(6)cm. sunt cele 2 triunghiuri asemenea? daca da stabileste perechile de unghiuri congruente

To prove the similarity of triangles, the first thing you must show are the following equalities:
 ((AB) / (A'B ')) = ((AC) / (A'C')) = ((BC) / (B'C '))
 For example for the first equality
 ((3) / (5.2)) = ((2.6) / (6))
 0.57 = 0.43
 Then, we prove that the triangles are NOT similar.
 Answer
 Triangles NOT similar.
