D. pairs 1 and 3
Polygons are congruent when they have the same size and shape. Corresponding sides and corresponding angles are congruent. One may be a rotation, reflection, or translation of the other.
Pair 1: each polygon is a reflection of the other about the center point of the figure. This pair is congruent.
Pair 2. corresponding sides are not congruent. This pair is not congruent.
Pair 3. each polygon is a translation of the other. This pair is congruent.
Pair 4. each polygon is a dilation of the other, so corresponding sides are proportional, but not congruent.
Pairs 1 and 3 are congruent
