Question

Are two line segments of same length are always congruent

Answer 1

HELLO DEAR... THE ANS IS YES
TWO LINES HAVING SAME LENGTH ARE CONGRUENT TO EACH OTHER

Answer 2

$<b>Line segments are the lines drawn between at least two given points.<b>$

Indeed, two line segments of same length are always congruent as if the distance between two points of both the line segments is same then for sure they will overlap each other completely.

What more do we need in congruency?

The line segments having same lengths will overlap each other completely so they are always congruent.
