Question

15. Given : RS and PT are altitudes of A PQR.
Prove that :
(i) A PQT - A QRS,
(ii) PQ X QS = RQ x QT.​

Answer 1

Step-by-step explanation:

in PQT and QRS

angle Q is common and angle T and S are 90

so by AA similarity we can say that triangles PQT and RQS are similar

2) if two triangles are similar then corresponding sides ratio will be same

so PQ/RQ= QT/QS

PQ*QS=RQ*QT

hence proved

in the question triangle PQT is similar to QRS is given please change that to RQS

Answer 2

Your answer is given above.

Hope you find it helpful.
