Well can we try and eliminate some? Like which one would it definitely not be?

anonymous · Answer

equilateral .. ? obtuse ?

anonymous · Answer

equilateral we can definitely eliminate.

anonymous · Answer

ok.

anonymous · Answer

is it a acute ?

anonymous · Answer

What we can use is a^2+b^2=c^2

which is 5^2+6^2=
can you find that?

anonymous · Answer

And then after you find that you'll take the third side (7^2 or =c^2). If the answer you get is less than C it is obtuse. If it is more it is acute. And if it is the same then it is a right triangle :)
