Which of the following conditions does NOT guarantee that two triangles are congruent?
Show answer & explanation
Correct answer: D
Explanation
The valid rules for the congruence of triangles are:
SSS (Side-Side-Side)
SAS (Side-Angle-Side)
ASA (Angle-Side-Angle)
However, SSA (Side-Side-Angle) does not guarantee congruence, because two different triangles can be formed given two equal sides and a non-included angle.
