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.
