How many different triangles can be formed from three line segments if two of the segments have the same length?

Question

(A) 0

(B) 1

(C) 2

(D) 3

(E) None of the above

I got (B) 1, is this correct?

Answer 1

You can form infinitely many triangles under these conditions, as long as the length of the third side is less than the sum of the lengths of the two equal sides. You can see this easily by drawing a few pictures.
