Question:--
In ∆ PQR, ∠ Q = 90° , Pq = 12, Qr = 5 and Qs is a Median. Find L(QS).
Answer:
In A PQR,
=> PR² = PQ2 + QR? (By Pythagoras theorem)
=> PR² = 122 + 5²
=> PR² = 144 + 25
=> PR² = 13²
=> PR = 13
In a right angled triangle, the length of the median on its hypotenuse is half the length of the hypotenuse.
. : (QS) = ÷ (PR)
= 1/2 (13)
= 6.5 units.
Hence,
The length of QR is 6.5 units .
