Q8 of 805 Page 13

To construct a triangle similar to ΔABC in which BC = 4.5 cm, ∠B = 45° and ∠C = 60°, using a scale factor of BC will be divided in the ratio

A. 3 : 4 B. 4:7


C. 3 : 10 D. 3 : 7



To construct a triangle similar to Δ ABC in which BC = 4.5 cm, ∠ B = 45° and ∠ C = 60°, using a scale factor of , BC will be divided in the ratio 3 : 4



Here, Δ ABC ~ Δ A’BC’


⇒ BC’ : C’C = 3 : 4


Or BC’ : BC = 3 : 7


Hence, the correct answer is option A.
