\(E\) and \(F\) are points on the sides \(PQ\) and \(PR\) respectively of a \(\Delta PQR\). For the following case, examine whether \(EF\) is parallel to \(QR\):
 
\(PQ = 5.4 \ cm\), \(PR = 7.2 \ cm\), \(PE = 1.8 \ cm\) and \(PF = 2.4 \ cm\)
 
Ans:
 
\(\frac{PE}{EQ} =\)
 
\(\frac{PF}{FR} =\)
 
Since \(\frac{PE}{EQ}\)
\(\frac{PF}{FR}\)
 
\(EF\) and \(QR\) are
.
Answer variants:
\(\frac{4}{55}\)
parallel
\(\frac{1}{2}\)
not parallel
\(\neq\)
\(=\)
