Question

what should be same in the line segments to be congruent??​

Answer 1

Answer:

Line segments are congruent if they have the same length. ... For line segments, 'congruent' is similar to saying 'equals'. You could say "the length of line AB equals the length of line PQ". But in geometry, the correct way to say it is "line segments AB and PQ are congruent" or, "AB is congruent to PQ".
