\(E\) and \(F\) are points on the sides \(PQ\) and \(PR\) respectively of a \(\Delta PQR\). For the following case, state whether \(EF||QR\):
\(PQ = 0.18 \ cm\), \(PR = 1.1 \ cm\), \(PE = 0.36 \ cm\) and \(PF = 2.2 \ cm\)
Ans:
\(\frac{PE}{EQ} =\)
\(\frac{PF}{FR} =\)
Since \(\frac{PE}{EQ}\) \(\frac{PF}{FR}\)
\(EF\) and \(QR\) are .
[Note: Enter the simplest fraction]
