If you are given two triangles and some measurements how easy is it for you to select the correct postulate to prove the triangles congruent?

To prove any two triangles congruent,
We can follow 5 ways: SSS, SAS, ASA, AAS and HL
SSS means 3 sides are equal.
SAS means any two sides and one angles are equal
ASA means 2 angles and 1 side between them are equal
AAS means 2 angles and 1 side are equal
HL means in the right angled triangle, the hypotenuse and the leg are equal.
So, in this way we can prove any two triangles are congruent.

So don't take my word i'm not exactly a mathematical person but i would assume a. because while selling the soap every month you increase in sells so you would by 11 percent. the you would get the factor 0.89 which if i had to guess would be the monthly profit over 11 probably wrong tho
