No, mainly because we do have all the questions explained here https://greprepclub.com/forum/official ... html#p3207And I didn't see this question before. Regards

The answer is A right? Sum of two angles in a triangle is greater than the third angle

A) Quantity A is greater. B) Quantity B is greater. C) The two quantities are equal. D) The relationship cannot be determined from the information given Let's test some possible values (angles) Case i: In the above case, y = 70, z = 110, x = 40 and w = 30 So, we get: QUANTITY A: x + w = 40 + 30 = 70 QUANTITY B: y + z = 70 + 110 = 180 In this case, Quantity B is greater Case ii: In the above case, y = 40, z = 50, x = 70 and w = 60 So, we get: QUANTITY A: x + w = 70 + 60 = 130 QUANTITY B: y + z = 40 + 50 = 90 In this case, Quantity A is greaterAnswer: D Cheers, Brent

I believe you're taking the rule regarding side LENGTHS in a triangle and extending it to work with ANGLES (which doesn't work). Cheers, Brent

But can u tell me how did u pick the correct angles to check. Is there any logic behind it ?

Just think about this, since we don't have ANY number associated with any of the angles, it's a total crapshoot. for all we know, it could be a scalene triangle, where x and w are 10 degrees each while y and z total to 160, or the complete opposite.

I just think in diagram case1 (Not quantity): angle A= 179.999999 case2 (Not quantity): angle B= 179.999999
D
