Is \(a + b > c\)?

(1) a, b, and c represent three different lengths of the sides of a certain triangle

(2) \(a^2+b^2=c^2\)

Statement 1

(1) a, b, and c represent three different lengths of the sides of a certain triangle

As a, b, and c represents three different sides of a triangle

|a-b| < c < a + b

Therefore c is always less than a + b.

The information is sufficient to answer the question Is \(a + b > c\)? - Yes !

Statement 2

(2) \(a^2+b^2=c^2\)

1) a = 3, b = 4 , c = 5

Is \(a + b > c\)? - Yes !

2) a = 3, b = -4 , c = 5

Is \(a + b > c\)? - No !

As we are getting two contradicting answers to the question, the statement alone is not sufficient.

Option A



How can length possibly be negative?

Option B says that the triangle is a right angled triangle and all the pythagorean triplets satisfy a+b>c

Great Question Afn24!

In a DS question, while evaluating Option A, B and D one has to evaluate the Statements independently. The information is combinedly evaluated ONLY when both the statements individually are not sufficient to answer the target question (i.e. when evaluating Option C).

Does statement 2 state anything on the nature of a, b, and c or does statement 2 tells us that a, b, and c represent the length of the triangle? That information is present in Statement 1 and should be ignored while evaluating Statement 2. In Statement 2, a, b and c can be any real number.

Hope that clarifies !
