How to prove congruency

1.	How to prove congruency
Answer» We can prove the congruency only by the four conditions and we have to see that what condition are suitable for the given triangles to prove their congruency - 1. SIDE SIDE SIDE (SSS)2. SIDE ANGLE SIDE (SAS)3. ANGLE ANGLE SIDE (AAS) and4. RIGHTANGLE HYPOTENUSE SIDE (RHS). Firstly we have to see all the sides and angles of two triangles which are equal and write any three same things and write his congruence rule.
