Question

in angel PQR ,RIGHT ANGLED AT Q .A POINT S IS TAKEN ON THE SIDE PR SUCH THAT PS=SR AND QR=QS.FIND THE MEASURE OF ANGLE QRS.

Answer 1

Answer: we know that S is any point on PR and SP = SR Then S is mid point of PR.

∆PQR is right triangle and right angle at Q, We also know that angle in semicircle is 90°.

That means S is centre of circle and passing through the the P,Q and R so that SP =SQ =SR is a radius of circle ...........(1).

But QS = SR is Given in question , so we say that from equation no.1

QS =SR = QR. .........(2)

From equation 2

∆ QSR IS Equilateral triangle.

So angle QRS is 60°.
