In parallelogram PQRS, O is the mid point of SQ. Find `angle`S, `angle`R, PQ, QR and diagonal PR.

In the given figure, PQRS is a parallelogram. If X and Y are mid-point of PQ and SR respectively and diagonal SQ is joined. Find the ratio of area of (||gm XQRY) : " area "(Delta QSR)

Construct a parallelogram PQRS with PR=3 cm , QS=4.2 cm, and the angle between the diagonals are equal to 75^(@) ,

In Delta PQR, s is a point in QR such that angle PQS= angle SPR show that angle PSR= angle QPR

In DeltaPQR,Pq=PR and S is the mid-point of PQ. A line drawn from S parallel to QR, intersects the line PR at T. Prove that PS = PT.

In triangle PQR , S and T are mid-points of PQ and PR, respectively. If angle QPR = 75^@ and angle PQR = 40^@ , then angle TSQ is: triangle PQR में, S और T क्रमशः PQ और PR के मध्य-बिंदु हैं, यदि angle QPR = 75^@ और angle PQR = 40^@ तो angle TSQ है :

In DeltaPQR, point S is the midpoint of side QR. If PQ =11, PR =17 PS =13 , find QR.
