The correct options are
A UQ = TR
C △PUQ≅△STR
Since, PQRSTU is a hexagon with all sides equal,
i.e., PQ = QR = RS = ST = TU = UP
and ∠P = ∠Q = ∠R = ∠S = ∠T = ∠U
∴ In triangles, △PUQ and △STR
PQ = UP = RS = ST
and ∠P = ∠S
Hence, by SAS criterion for congruency of triangles
△PUQ ≅ △STR
So, UQ = TR (corresponding parts of congruent triangles)
