Triangle, test OG

[isisalaska]

Perimeter of an isosceles right triangel is 16=16(square root) 2
why the hypotenuse is 16 an dnot 16(square root)2, I though is was a 1:1:square root2 triangle...

I think this is a tricky question but you can write 16sqrt(2) like
8sqrt(2)+8sqrt(2) so these are the right sides and hypot. is 16
