Question

Sasha made four models of airplane wings, as shown below.



Which model is a right triangle?

Model B

Model A

Model D

Model C

Answer 1

please help me

Answer 2

the one where \(a^2+b^2=c^2\)

Answer 3

a huge hint is that you will get it on the first try, but lets do one that works and one that doesn't work

Answer 4

5in 6in 7in D

Answer 5

can we do it step by step

Answer 6

One of the triangle with
\(p^2+b^2=h^2\)
Where, p=perpendicular
b=base
h=hypotenuse

Answer 7

for example 5 6 7 does not work we check
\(5^2+6^2=7^2\)

Answer 8

\[25+36=49\]
\[61=49\] no, \[61\neq 49\] so this one is not a right triangle

Answer 9

I think model A is the answer

Answer 10

lets try the one that does work
\[3,4,5\]
\[3^2+4^2=5^2?\]
\[9+16=25\]
yes, since \(9+16=25\) we know the triangle with sides \(3,4,5\) is a right triangle

Answer 11

Becoz \(3^2+4^2=5^2\)
\(9+16=25\)
\(25=25\)

Answer 12

it s model A

Answer 13

yeah!
