Question

Why is AAA criterion not there in congruence of triangles ???​

Answer 1

Knowing only angle-angle-angle (AAA) does not work because it can produce similar but not congruent triangles. When you're trying to determine if two triangles are congruent, there are 4 shortcuts that will work. Because there are 6 corresponding parts 3 angles and 3 sides, you don't need to know all of them.

Mark as brainliest answer.

Answer 2

AAA criteria is not applicable for congruence of triangle. It can be

understood by following example.

In the above figure, P=A

(here A refers to angle A)

also, R=C

and Q=B

but it is clearly visible that the sizes of the ∆s are not same i.e. ∆ABC is not congruent to ∆PQR.

THEREFORE AAA CONGRUENCE CRITERIA DOESN'T EXIST..

(but if you have studied class 10 then you will know that ∆ABC~∆PQR)
