# In ∆ PQR, D is the mid-point of QR

PM is _

PD is _

Is QM ≠ MR?

**Solution:**

Let’s visually model this problem.

First, check PM is perpendicular on QR or not, then check PD divides QR into equal parts or not, and then find the mid-point of QR.

According to this model, the result PM is perpendicular on QR. Then, PD divides QR into equal parts and D is the mid-point of QR.

Given, PM is perpendicular on QR.

Therefore, PM is altitude. Also, D is the mid-point of QR.

QD = DR as PD is median

No, QM ≠ MR because D is the mid-point of QR.

**Video Solution:**

## In ∆ PQR, D is the mid-point of QR . PM is _ PD is _Is QM ≠ MR?
