Which of the following is not a sufficient condition for two triangles to be congruent?
a.
AAS
b.
SSS
c.
SAS
d.
SSA
Correct answer: D
The side-side-angle (SSA) condition does not imply congruence of triangles. The other conditions — angle-angle-side (AAS), side-side-sided (SSS), and side-angle-side (SAS) — are sufficient for two triangles to be congruent.
