In Delta PQR "seg" PS "is median of" Delta PQR. "And" PT bot QR , (ii) PQ^(2) = PS^(2) - QR xx ST + ((QR)/2)^(2)

In Delta PQR "seg" PS "is median of" Delta PQR. "And" PT bot QR, (i) PR^(2) = PS^(2) + QR xx ST + ( (QR)/2)^(2)

In the adjoing figure, seg PS is the median of DeltaPQR and PTbotQR. i. PR^(2)=PS^(2)+QRxxST+((QR)/(2))^(2)

In the adjoing figure, seg PS is the median of DeltaPQR and PTbotQR. i. PR^(2)=PS^(2)+QRxxST+((QR)/(2))^(2)

Angle Q and R of a DeltaPQR are 25^(@) and 65^(@) . Write which of the following is true (i) PQ^(3) + QR^(2)= RP^(2) (ii) PQ^(2) + RP^(2)= QR^(2) (iii) RP^(2) + QR^(2)= PQ^(2)

PQ is line segment 12cm long and R is a point in its interior such that PR=8cm, then find QR,PQ^(2)-PR^(2) and PR^(2)+QR^(2)+2PR.QR

PQ is a line segment 12cm long and R is a point in its interior such that PR=8cm, then find QR,PQ^(2)-PR^(2) and PR^(2)+QR^(2)+2PR*QR

If pq + qr + rp = 0 , then what is the value of (p^(2))/(p^(2) - qr) + (q^(2))/(q^(2) - rp) + (r^(2))/(r^(2) - pq) ?

In PQR,QM perp PR and PR^(2)-PQ^(2)=QR^(2). Prove that QM^(2)=PM xx MR
