reemii · Answer

if it is a right triangle, can you spot the length of the hypothenuse ?

anonymous · Answer

Please elaborate.

reemii · Answer

can the hypothenuse be the side of lengt 2?

anonymous · Answer

No, because it's not the longest side, correct?

reemii · Answer

that's it, now isn't it possible to apply the theorem and decide whether it is a right triangle or not if the Pythagorean formula works

anonymous · Answer

I have 8^2= 2^2 + (2√ 15)^2, correct?

reemii · Answer

yes so the frmula works, i think we can conclude that triangle is a right triangle.

anonymous · Answer

Not necessarily, the equation has to come out equivalent.
