Is quadrilateral ABCD a rectangle?
(1) The diagonal AC divides ABCD into two congruent triangles.
(2) ABCD has at least two right angles and at least two equal sides.
(1) statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked;
(2) statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked;
(3) BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked;
(4) EACH statement ALONE is sufficient to answer the question asked;
(5) statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.

BTW, what is right, "Sufficient condition to be a rectangle" or "Sufficient condition for a rectangle"
