Question

If M, N are points on the sides PQ and PR respectively of ∆ PQR
and given PQ = 15.2 cm, PR = 12.8 cm, PM = 5.7 cm, PN = 4.8 cm.
State whether MN || QR

Answer 1

Step-by-step explanation:

first we need to prove that both the triangles PMN and PQR are similar then with the formula for the similarity we

can prove that MN || QR

FORMULA IS

PM/PQ=MN/QR
