Question

In triangle PQR angle Q =90 degree,PQ 12,QR 5 and QSis a median.find length QS

Answer 1

Here ur answer my friend.

Answer 2

Answer :

when we draw median of right angled triangle the centroid is on the mid point of hypotenuse. In triangle PQR the centroid is at S,which is the mid point of PR.

PR2 = PQ2 + QR2

     = 122 + 52 = 144 + 25 = 169

Therefore PR= 13

RS = PS = 13/2=6.5

Sis the centroid , RS =PS =QS=6.5
