If BCDE is congruent to OPQR, then DEis congruent to _______.
QR
If BCDE is congruent to OPQR, then DE is congruent to QR.
To determine what DE is congruent to, we need to consider the given information that BCDE is congruent to OPQR. In congruent figures, corresponding parts are equal in measure.
In this case, we can conclude that DE is congruent to QR. This is because "DE" corresponds to the same position as "QR" in the congruent figures BCDE and OPQR. Therefore, DE is congruent to QR.
