Correct! The issue here is whether quadrilateral \$\$ABCD\$\$ _must_ be divided into two congruent triangles by diagonal \$\$BD\$\$. By finding even one quadrilateral that cannot be divided into two congruent triangles, you have proved that both statements are insufficient. If both statements are true, then the quadrilateral is either an isosceles trapezoid (a trapezoid whose legs are of equal length) or a parallelogram. By definition, every parallelogram has congruent sides and therefore can be divided into 2 congruent triangles. However, an isosceles trapezoid meets conditions 1 and 2 but when divided by line \$\$BD\$\$, the resulting triangles are not congruent.
