Question

daca ipotenuza unui triunghi dreptunghic isoscelbeste 4√2 atunci aria triunghilui este

Answer 1

Rezolvarea exercitiului:

Answer 2

   
Iti dau doua metode de rezolvare:

M1:  
Calculam lungimile catetelor:

[tex]\displaystyle\\ c_1 = c_2 = \frac{Ipotenuza}{ \sqrt{2} } =\frac{4\sqrt{2}}{ \sqrt{2} } = 4~cm\\\\ A = \frac{c_1 \times c_2}{2} = \frac{4\times 4}{2} = \frac{16}{2}=\boxed{\bf8~cm^2}[/tex]


M2:
Calculam aria folosindu-ne doar de ipotenuza:

[tex]\displaystyle\\ A = \frac{(Ipotenuza) ^2}{4}= \frac{(4 \sqrt{2} )^2}{4}= \frac{16\times 2 }{4}= \frac{32 }{4}= \boxed{\bf8~cm^2}[/tex]
