Proving two triangles congruent allows us to establish the correspondence between their corresponding parts, such as corresponding angles or corresponding sides, which in turn assists in proving parts of the triangles congruent.
Proving two triangles congruent can help prove parts of the triangles congruent by using corresponding parts of congruent triangles (CPCTC) theorem, which states that corresponding parts of congruent triangles are congruent.
Two triangles are congruent when they have the same size and shape. By proving that two triangles are congruent, you can conclude that their corresponding sides and angles are also congruent.
