# 1.    In  $\small \Delta PQR$,  D is the mid-point of  $\small \overline{QR}$ .            $\small \overline{PM}$  is _________________.            PD is _________________.            Is $\small QM=MR$ ?

$\small \overline{PM}$  is the Altitude of the triangle.
No, $\small QM\neq MR$. As QD = DR.
