is there any congruence named as AAA? if yes pls explain it.

Dear Student,
 
No, there is no congruency criterion called AAA (Angle-Angle-Angle) congruency.
This can be explained as,
Here, all the angles of ∆ABC are equal to that of ∆PQR.
But, ∆ABC is not congruent to ∆PQR    [Since they are of different size]
 
But, there is similarity criterion called AAA similarity criterion as you see that the above two triangles are similar.
 
Hope! You got the answer.
Cheers!

No, there is no congruence called AAA as in angle-angle-angle. This is because a triangle may have equal angles, but they may not be of the same size. Hence there is no congruence criteria as AAA.
