There's the picture again if you can't see it

A triangle is right if and only if it satisfies the pythagorean theorem, a^2 + b^2 = c^2.  Can you figure it out from here?

anonymous · Answer

Okay I used that, but none of them were equal.

anonymous · Answer

the fourth triangle...
hey remember in a triangle the hypotenuse i.e. c is the biggest side and if u apply a2+b2=c2 on the 4th triangle(here c is the biggest side that is 25).. now a=7 and b=24 so so a2=49 and b2= 576
therefore a2+b2 = 49 +576 = 625  which is equal to c2....

Ohh I see. I think I added wrong or forgot something in there. Thank you so much!
