Open in App
Solution
The correct option is C AAA
Rules for congruency of triangles are:
Among the given options, AAA is used to check the similarity of the triangles.
Example: All equilateral triangle have same angles i.e. 60∘ but they can be of different sizes.
Hence, AAA is a check for similarity but not for congruency.
