Question

9. In parallelogram PQRS, mLQ=130°. Find the
measures of other angles of PQRS.
​

Answer 1

Answers :

To solve these question, follow :

Given : angle Q = 130 °

To find : angle P, R, S?

Proof : In parallelogram PQRS

angle Q = angle S ( opposite angles of parallelogram are equal)

therefore, Angle S = 130°

Angle Q + Angle P = 180° ( adjacent angles are supplementary i. e. sum is equal to 180 )

therefore, 130 + Angle P = 180°

Angle P = 180 - 130

Angle P = 50°

Angle P = Angle R ( opposite side of parallelogram are equal)

Angle R = 50°
