Answer
(i) In △ABC,
AB is the greatest side, the greatest side has greatest angle opposite to it.
∴ ∠C is the greatest angle.
Hence, ∠C is the greatest angle.
(ii) In △ABC,
BC is the smallest side, the smallest side has smallest angle opposite to it.
∴ ∠A is the smallest angle.
Hence, ∠A is the smallest angle.
