Answer: B. \(\overline{PQ}\ and\ \overline{RS}\) have the same length.
Step-by-step explanation:
We have given that \(\overline{PQ}\cong\overline{RS}\), where \(\overline{PQ}\ and\ \overline{RS}\) are two line segments.
We know that if two line segments are congruent or equal then their lengths are equal.
Therefore, if \(\overline{PQ}\cong\overline{RS}\) then it shows that \(\overline{PQ}\ and\ \overline{RS}\) have the same length.
Hence, B is the right answer.
