Official Solution:


We’ll go for LOGICAL because the statements relate to common triangle rules.

We’ll examine the information given in the statements, using what we know about triangles: (1) is true for any side of any triangle – no new information (meaning, that’s not enough). (A) and (D) are eliminated. (2) is the Pythagorean Theorem – meaning, AB is the hypotenuse, which is the longest side. That’s exactly what we were looking for. (C) and (E) are eliminated.


Answer: B

Hi,

I thought that Pythagoras was only true for any RIGHT triangle and the question does not explicitly say that the triangle is RIGHT and so I picked E. Am I misreading the question?

Thanks
