Question

Stabiliti daca triunghiul ABC este dreptunghic cu m(∡BAC)=90° stiind ca :

a) AB=6√3 cm , AC=6√6cm si BC=18cm
b) AB=8√3cm , AC=6√3cm si BC=10√2
c) AB=4√3cm , AC=3√3cm si BC=5√3
d)AB=9√2cm , AC=12√2cm si BC=15√3

Answer 1

AB^2+AC^2=BC^2=)(6r3)^2+(6r6)^2=324=)BC=r324=18=)trABC dr-A=) trABC este dreptunghi
