Question

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

Answer 1

Given: QD =DR

Median of a triangle is a line segment joining a vertex to the midpoint of the opposing side .
$\therefore$PD is median.

$\overline{PM}$ is altitude as it is perpendicular to QR.
QM $\ne$ MR as D is the mid-point of QR.
