Question

In fig., PQRS is a parallelogram in which ∠PSR = 125^o, ∠RQT is equal to

• A. 125^o
• B. 55^o
• C. 65^o
• D. 75^o

Answer 1

The correct option is B

55^o

∠PSR = ∠RQP = 125^o ( since PQRS is a parallelogram, opposite angles will be equal)

∠PQT = 180^o (PQT is a st. line)

∠PQR + ∠RQT = 180⁰

125⁰ + ∠RQT = 180⁰

∠RQT = 55^o
