`DeltaABC and DeltaPQR` are congruent if _______A. AB=BC=AC and PQ=QR=PRB. `angleA=angleP, angleB=angleQ and angleC=angleR`C. `AB=PQ,BC=QR and angleB=angleQ`D. `AB=PR, BC=RT and angleC=angleT`

Answer» Correct Answer - C
(a) `implies` Two equilateral triangle need not be equal.
(b) `implies ` Corresponding sides of the triangles need not be equal.
(c ) `implies` By SAS congruence property, `DeltaABC=DeltaPQR`.
Hence, the correct option is (c ).
