Answer 1

sides-PQ , PS , QR , RS

Angles- ∠PQR , ∠QRS , ∠RSP , ∠QPS

Vertices- P , Q , R, S

Diagonals-QS , PR

Adjacent sides-PQ nd QR , QR nd RS , RS nd PS , PS nd PQ

Adjacent angles- ∠P nd ∠Q ,∠Q nd ∠R ,∠R nd ∠S , ∠P nd ∠S

Opoosite sides-PQ nd RS , QR nd PS

Opposite angles-∠P nd ∠R , ∠Q nd ∠S

Answer 2

In PQRS is a Quadrilateral .

1 )
i ) Four sides : PQ , QR , RS , SP

ii ) <P,<Q,<R,<S

iii ) P,Q,R,S are vertices

iv ) PR , QS is two diagonals

2 )

i ) (<P,<Q ) , ( <Q,<R),(<R,<S),(<S,<P) are pair

of adjacent angles.

ii ) ( PQ , SR ) , ( PS , QR ) opposite sides

iii ) ( <P,<R ) , ( <S,<Q ) pair of opposite

angles.
