Answer 1

1 and 3

Answer 2

My bad, it is A. oops.

Answer 3

I must be missing something, because I do not that any of these apply.

Answer 4

Apply Pythagoras equation.
Notice in the first triangle "A, B, and C" is stated, in the second "C" is not..

Answer 5

My bad should've put *Pythagorean equation

Answer 6

Well you can show a squared + b squared is KL squared. But that does not prove it is equal to c. For c to be the sum of a squared and b squared, it would have to be a right triangle --- but that is exactly what we are trying to prove. So in other words, this would be circular because we would have to assume the conclusion.

Answer 7

"Triangle KML is a right triangle, so a^2+b^2 = KL^2

If we can show that KL = c, then we can use the pythagorean theorem to show that triangle KML is a right triangle.

So it's "Prove that KL is equal to c by Pythagorean Theorem."- Jim Thomps.

Answer 8

The third and fourth obviously would disprove that it is a right triangle. So far as I understand the second option, it is not pertinent. You cannot prove KL = c with the first one, but if you were given KL=c then you could prove the first one is a right triangle.

I'm pretty sure this just a bad item with no correct answer.
