Final answer:
The correct statement for congruent triangles ∇PQR and ∇ASTU is likely option A, which asserts that side PQ is equal to side ST, consistent with the congruence of the triangles.
Step-by-step explanation:
It appears that the original question involves congruent triangles, as indicated by ∇PQR ≈ ∇ASTU. When two triangles are congruent, all corresponding sides and angles are equal. Therefore, the correct statement must be one that asserts the equivalence of corresponding parts.
Option A (PQ = ST) is likely the correct one, as it suggests that side PQ in triangle PQR is equal to side ST in triangle ASTU, which is a requirement for congruent triangles. The other options are not coherent or relevant within the given context, as they may be referencing angles or points not clearly defined in the question.
