Question 7 (Choice - 2) In the given figure, AD = 2cm, BD = 3 cm, AE = 3.5 cm and AC = 7 cm. Is DE parallel to BC ? Here, š‘Øš‘«/š‘«š‘©=šŸ/šŸ‘ š‘Øš‘¬/š‘¬š‘Ŗ= š“šø/(š“š¶ āˆ’ š“šø) =3.5/(7 āˆ’ 3.5) =3.5/3.5=šŸ Since š‘Øš‘«/š‘«š‘© ≠ š‘Øš‘¬/š‘¬š‘Ŗ ∓ Ratio of the two sides is not same, So, we cannot use Basic Proportionality Theorem ∓ DE is not parallel to BC
