In the figure above, segments AD and AC divide angle EAB into three nonoverlapping angles that are equal in measure. Are AE and AB equal in length?

(2) AC = CB

Answer is E because we don't know if the bottom line is straight or not.

Hmmm... instructions say diagrams are drawn to agree with information in the question stem (though not necessarily in the two statements). So I think we can assume the line is straight.

OE is A. I'm not sure why it's not D though. Why is statement 2 insufficient? Seems to me like it ought to be enough.

From 1. Yes it is sufficient
2 is insufficient

Explainations later

agree that it makes sence to be A
B) is incorrect. angle EAB is separated into three parts and each part is equal to Q/3. From B) angle EBA is also equal to Q/3. Then for the statement that AE=AB to be true angle EBA should equal to angle AEB both equal to Q/3. Now angle AEB=180-4Q. Note that when Q=36 degrees the triangle is isosceles and B) is suff. BUt if Q is different from 36 degrees then B) is insufficient so A) is the only correct choice.

(2) AC = CB

(1) since <EAD, <DAC, and <CAB are equivalent having sides AD = AC will have to make AE = AB so SUFFICIENT

(2) if sides AC = AB, although <EAD, <DAC, and <CAB are equivalent side AE can continue to extend longer than AC or AB. There is no information here that states segment ADCB forms a linear line so it is INSUFFICIENT

Can someone please explain why A is sufficient?

Got A without any problem, but why statement II is not sufficient is still beyond me. Can you please elaborate on your explanation? Thanks!
