Which model is a right triangle?

Model C

Model A

Model B

Model D

I am pretty sure C is, if I use the pythagoras theorem for a right triangle of a^2+b^2=c^2
Perhaps?

Answer 1

The answer is A, model C.

Answer 2

Well, what do need help with? since you already know the answer..

Answer 3

I'm just making sure I'm doing it right lol so many formulas to keep track of .-.
My "reply" was supposed to be a question haha

Answer 4

I was just clarifying the "c" from my original post.

Answer 5

Okay let's do it one one to see which triangle is right ok?

Answer 6

Okay! :)

Answer 7

A. = 1 + 81 ≠ 100
B. = 4 + 9 ≠ 25
C. = 81 + 144 = 225
:D lol

Answer 8

lol, you have already done it

Answer 9

haha :D I really wanted to make sure though bc my brain is like Dx haha

Answer 10

Okay; indeed you're right. It's C, you understand why?

Answer 11

\[12^2 +9^2 = 225\]
which is equal to \(15^2\)

Answer 12

I think because a^2 + b^2 = c^2
I just did it from the smallest number to the largest and plugged the numbers into the x

Answer 13

oh yess. Thanks Mimi :3

Answer 14

It has to be equal
for instance its the not the first one forgot \(1^2+9^2 = 82\) which is not equal to \(10^2\)

Answer 15

And you're welcome! :D

Answer 16

not the first one because*
