hartnn · Answer

you can use pythagoras theorem, can you apply it here ?

tkhunny · Answer

If all else fails, like remembering the relationships of a 45-45-90 right triangle, you can use Pythagoras!

a2 + b2 = c2?

irishboy123 · Answer

a^2 + b^2 = c^2?

i am sure that is you meant - so yes!

hartnn · Answer

yes, use it.

hartnn · Answer

a= 3 root 2, b= 3 root 2 , find c= hypotenuse

irishboy123 · Answer

Pythagoreas is amazing (not invented or created by Pythagoreas) as it allows us to combine things that are pointing or moving or happening in totally different directions.  Pythagoreas works in 3 dimensions, Einstein drew heavily on it.

You've now got this power at your fingertips.  as @hartnn says, use it dude!!!

what is $(3\sqrt2)^2=...?$

anonymous · Answer

*facepalm*

anonymous · Answer

it =6

hartnn · Answer

6 what ? the hypotenuse ?

hartnn · Answer

yes, hypotenuse = 6 is correct :)

tkhunny · Answer

Now, if you remember what is special about the 45-45-90 right triangle, you just write it down, rather than go through Pythagoras.

$3\sqrt{2}\cdot\sqrt{2} = 3\cdot 2 = 6$
