Final answer:
To determine which pairs of polygons are congruent, details about their shapes and sizes are necessary. Without them, we cannot identify congruent pairs.
The correct option is 1.
Step-by-step explanation:
The question you have asked about which pairs of polygons are congruent cannot be definitively answered without additional information, such as illustrations or descriptions of the polygons in the pairs being referred to.
Congruent polygons are those that are identical in shape and size, having corresponding sides and angles that are equal. Therefore, to determine which pairs are congruent, one would need to compare such features to confirm congruency.
The correct option is 1
