Official Solution:


The triangle is equilateral when all of its sides have the same length.

Statement (1) by itself is insufficient. We don't know anything about the length of the other sides.

Statement (2) by itself is insufficient. Knowing that \(BC + AC = 2\), doesn't give us enough information to be sure that the triangle is equilateral. Suppose \(BC=1.1\) and \(AC=0.9\).

Statements (1) and (2) combined are insufficient. Combining the two statements doesn't ensure that BC and AC equal exactly 1 each.


Answer: E
