Question

dacă ∆ABC ∆MNP, AB=8cm, MN=2cm, N P=4cm,
Aflați lungime laturii BC​

Answer 1

Răspuns:

BC = 16 cm

Explicație pas cu pas:

∆ABC ~ ∆MNP

AB=8cm, MN=2cm, NP=4cm

$\frac{AB}{MN} = \frac{BC}{NP} \\ \frac{8}{2} = \frac{BC}{4} = > BC = \frac{8 \times 4}{2} = \frac{32}{2} \\ = > BC = 16 \: cm$
