Answer is A.

(1) Gives you a right triangle with vertices (0,3), (4,0). Third vertex is (0,0) since the question itself says that its a right angled triangle.

(2) Does not help since the side can be in any of the 4 quandrants.

IMO C...must say v good and tricky ques...i was tempted to mark A...
let me know if i am missing something...here s my reasoning

wat if the line joining (0,3) and (4,0) is not the hypotenuse???

2. alone cant help us...

1.+ 2. tells us that indeed line joining 0,0 and 4,0 can be the base of triangle..

hence C

I think it should be E.

1. Third vertex can be (4,3) or (0,0)

2. Doesnt help much

1&2 - we already know that one side is 4 (stmt1), so info in 2 doesnt help.
