PQRS is a trapezium in which PQSR and P = 130°, Q = 110°, then R is equal to :

In a trapezium the adjacent angles in the non-parallel sides are supplementary

∠ R + ∠ Q = 180⁰

⇒ ∠ R = 180⁰-110⁰

⇒ ∠ R = 70⁰

A parallelogram PQRS is constructed with sides QR = 6cm. PQ = 4cm and PQR = 90°. Then PQRS is a

The angles P, Q, R and S of a quadrilateral are in the ratio 1:3:7:9. Then PQRS is a

The number of sides of a regular polygon who’s each interior angle is of 135° is

If a diagonal of a quadrilateral bisects both the angles, then it is a
