By applying which of the following criteria can two triangles NOT be proved congruent?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. angle-angle-angle.
The angle-angle-angle criterion cannot be used to prove two triangles are congruent.
AAA (Angle-Angle-Angle) only proves that two triangles are similar (same shape), not necessarily congruent (exactly the same size and shape). In AAA similarity, Corresponding angles of triangles are equal, but the lengths of the sides can be different. So, it does not prove them to be congruent.
