Question

Calculati cu teorema lui Pitagora:
Fie triunghiul ABC, cu A = 90°
a) Daca AB = 16 cm , AC= 12 cm, calculati BC​​

Answer 1

CB-ipotenuza

Teorema lui Pitagora:ipotenuza^2=o cateta ^2+cealalta cateta^2

CB^2=AC^2+AB^2

CB^2=12^2+16^2

CB^2=144+256

CB^2=400

CB=radical din 400

CB=20 cm

Answer 2

T. P.

ip^2=c1^2+c2^2

In trABC, A=90°=>conform T. P. BC^2=AB^2+AC^2=>BC^2=16^2+12^2=256+144=400

BC^2=radical din 400=>BC=20
