# In ∆ PQR, D is the mid-point of QR.

PM is _____.

PD is _____.

Is QM ≠ MR?

**Solution:**

Let’s visually model this problem.

According to this model, PM is perpendicular on QR.

Also, PD divides QR into equal parts as D is the mid-point of QR.

Therefore, PM is altitude.

Also, D is the mid-point of QR.

Therefore, QD = DR and hence PD is the median

Yes, QM ≠ MR because D is the mid-point of QR.
