10 Please explain how both the statements are not required? Hi agnok, we know sum of two sides to be 10 so the possibilities of 2 sides can be (5,5),(4,6),(3,7),(2,8),(1,9) coming to Choice 2 : Insufficient Hope it helps u Thanx GMAT Tutor Joined: 24 Jun 2008 Posts: 4085 Re: triangles [#permalink]

10 Please explain how both the statements are not required? Where is this question from? It doesn't make any logical sense as a DS question, because it's impossible to know what information would be sufficient, and there is no unique correct answer to the problem. Simplifying the problem for illustration, if, say, you were asked: The integer x lies between which two numbers? Is Statement 1 sufficient? Statement 2? The question makes no sense, since there is no single answer - x lies between a lot of different pairs of numbers. So the GMAT could never structure a DS question like the one in the original post.

I understand perfectly well what the question is asking, and it makes no difference if it's geometry or algebra. If you have, say, a 3-4-5 triangle, and I ask "between what two numbers is the measure of the longest side?", then what is the answer? There isn't one unique correct answer; 5 is between 4 and 6, but it's also between 1 and 1000. It doesn't make sense to ask this as a DS question. Clearly the question designer was trying to test the triangle inequality in a DS question, but as it's written, the question doesn't make any sense as a Data Sufficiency problem, and you could never see it on the GMAT.

In original posted question, it doesn't say integer also. So sides are infinite 1.1; 2,1 etc Manager Joined: 17 Nov 2009 Posts: 208 Re: triangles

All, This question is from Learning Express's GMAT Book. I did not understand it myself hence asked for your assistance. Intern Joined: 07 Sep 2010 Posts: 25 Re: triangles

Hi All, The measure of a
side of triangle has to be less than the sum of the other two sides of the triangle and greater than zero. KUDOS KUDOS KUDOS Guys!!! Math Expert Joined: 02 Sep 2009 Posts: 86907 Re: triangles

This question does not make any sense. I wouldn't recommend to study it. Re: triangles [#permalink] 11 Sep 2010, 22:50 What two numbers can the third side of a triangle be in between when two sides are 6 and 10?The Triangle Inequality Theorem can also help you find the range of the third side. The two given sides are 6 and 10. The third side, , must be between 10 − 6 = 4 and 10 + 6 = 16 . In other words, the range of values for is 4 < s < 16 .
Between what two numbers must the length of the third side fall 8 and 11?8 + 11 = 19 cm. Thus, the length of the third side falls between 3 cm and 19 cm.
Between which two numbers can the length of third side of a triangle fall if two of its sides measure 4cm and 8cm?So, the answer is 2 < third side < 14. The third side lies between(2,14).
