PQR is an equilateral triangle. MN is drawn parallel to QR such that M is on PQ and N is on PR. If PN = 6 cm, then the length of MN is:
A. 3 cm
B. 6 cm
C. 12 cm
D. 4.5 cm
Answer: Option B
Solution (By Examveda Team)
∵ ΔPQR ∼ ΔPMN∵ ΔPQR is equilateral
∴ PQ = PR = QR

So, ΔPMN must be equilateral
So, MN = PN = 6 cm
