\(E\) and \(F\) are points on the sides \(PQ\) and \(PR\) respectively of a \(\Delta PQR\). For the following case, state whether \(EF||QR\):
\(PQ = 1.28 \ cm\), \(PR = 2.56 \ cm\), \(PE = 0.18 \ cm\) and \(PF = 0.36 \ cm\)
Ans:
\(\frac{PE}{EQ} =\)
\(\frac{PF}{FR} =\)
Since \(\frac{PE}{EQ}\) \(\frac{PF}{FR}\)
\(EF\) and \(QR\) are .
Answer variants:
\(=\)
\(\frac{4}{55}\)
not parallel
\( \frac{9}{55}\)
parallel
\(\neq\)
