MCQ
$\text{In} \ \triangle\text{PQR},$
- A$PQ - QR > PR$
- B$PQ + QR < PR$
- ✓$PQ - QR < PR$
- D$PQ + PR< QR$
✓
Answer
Correct option: C.
$PQ - QR < PR$
As we know, sum of the lengths of any two sides of a triangle is always greater than the length of the third side.
$\text{In} \ \triangle\text{PQR,}$ $PR + QR > PQ$
$\Rightarrow PR > PQ - QR$
$\Rightarrow PQ - QR < PR$
