Answer :

Draw a Line segment AD \(\perp BC \). It is an altitude for this triangle. Here we observe that length of QS and SR is also same. So PS is also a median of this triangle.

- Q.1 In \(\triangle \)PQR, D is the mid-point of \(\overline{QR} \) , (i) \(\overline{PM} \) is.......... (ii) \(\overline{PD} \) is........... (iii) Is QM = MR?
- Q.2 Draw rough sketches for the following: (a) In \(\triangle \)ABC, BE is a median. (ib) In \(\triangle \)PQR, PQ and PR are altitudes of the triangle. (c) In \(\triangle \)XYZ, YL is an altitude in the exterior of the triangle.
