If BCDE is congruent to OPQR, then line DE is congruent to _______.
If BCDE is congruent to OPQR, it means that every corresponding side and angle of the two figures are congruent. Therefore, line DE is congruent to line QR.
If BCDE is congruent to OPQR, it means that these two sets of line segments have the same length. Therefore, if line BCDE is congruent to line OPQR, then line DE must be congruent to line QR.
To determine what line DE is congruent to, we need to understand the concept of congruence. In geometry, congruence refers to when two objects have the same shape and size. In this case, we are given that line segment BCDE is congruent to line segment OPQR.
To find the line segment that is congruent to DE, we need to look for another line segment in the same figure that has the same length as DE.
Given that BCDE is congruent to OPQR, we can conclude that DE is congruent to QR. So, line DE is congruent to line QR.
