In the fig,PQR and QST are two right triangles ,right angled at R and T respectively .Prove that QR= QS= QP× QT
Answers
QR * QS = QP* QT, PQR and QST are two right triangles ,right angled at R and T respectively
Step-by-step explanation:
Correction
QR * QS = QP* QT
in ΔPQR & ΔSQT
∠R = ∠T = 90°
∠Q = ∠Q (common)
=> ΔPQR ≈ ΔSQT
=> QP/QS = QR/QT = PR/ST
QP/QS = QR/QT
=> QP * QT = QR * QS
=> QR * QS = QP* QT

The correct question is In the Fig,PQR and QST are two right triangles ,Right angled at R and T respectively. Prove that QR * QS = QP× QT.
Step-by-step explanation:
Given:
Figure given below in attachment.
ΔPQR,
∠R = 90°
ΔSQT,
∠T = 90°
To Prove That:
QR * QS = QP * QT
Proof:
In ΔPQR and ΔSQT,
∠PQR = ∠SQT (Common)
∠PRQ = ∠STQ (Right Angles)
ΔPQR ≈ ΔSQT (By A.A Similarity)
Cross Multiplying we get,
QR * QS = OP * QT
Hence Proved
