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.
