  1. If PQRS is a rhombus and ∠SPQ = 50°, then ∠RSQ is
    1. 55°
    2. 65°
    3. 75°
    4. 45°
Correct Option: B

On the basis of question we draw a figure of rhombus ABCD

In the rhombus PQRS,
PQ = QR = RS = SP
∠SPQ = 50°

∴ ∠PSQ = ∠PQS =
180° - 50°
2

∠PSQ = ∠PQS =
130°
= 65°
2

∠PSR = 180° – 50° = 130°
∠RSQ = 130° – 65° = 65°
