There are four ways to prove for congruency of two triangles.
1. All three corresponding sides are the same (Side - Side - Side / SSS property).
2. Two corresponding sides AND their included angle are equal (Side - Angle - Side / SAS property).
3. One corresponding side and ANY two included angles are equal (Angle - Side - Angle / ASA property).
4. [Special case, exclusive to right angled triangles] One right angle, the hypotenuse and one corresponding side are equal (Right Angle - Hypotenuse - Side / RHS property).
Note, however, that right-angled triangles can be proved by ANY of the four properties.
