Question

when rectangle abcd is reflected across line ef, the image is dcba. how do you know that segment ab is congruent to segment dc? a a rectangle has 2 pairs of parallel sides. b any 2 sides of a rectangle are congruent. c congruent parts of congruent figures are corresponding. d corresponding parts of congruent figures are congruent.

Explanation:

When a rectangle is reflected, the pre - image and the image are congruent. Segment AB and segment DC are corresponding parts of the congruent rectangles ABCD and DCBA. By the principle that corresponding parts of congruent figures are congruent, AB is congruent to DC.

Answer:

D. Corresponding parts of congruent figures are congruent.
