Question

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

Answer 1

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.
