Question

By which of the following criterion two triangles cannot be proved congruent ?

• A. AAA
• B. SSS
• C. SAS
• D. ASA

Answer 1

The correct option is A

AAA

Justification

AAA congruence criterion :- In this criterion we can draw two triangle which have three angles equal but in different size .

AAS stands for Angle-angle-side. When two angles and a non-included side of a triangle are equal to the corresponding angles and sides of another triangle, then the triangles are said to be congruent.

So, two triangles cannot be proved congruent by AAA.

Hence, the correct option is A.
