A triangle similar to given Δ A B C with sides equal to 3 4 of the sides of Δ A B C is constructed. B C ′ B C is equal to____. Options: A . &nbspBA′CA′ B . &nbspBA′BA C . &nbspBCAC D . &nbspBC′B3C′

Answer: Option B : B As Δ A B C ∼ Δ A ′ B C ′ , B C ′ B C = B A ′ B A = A ′ C ′ A C = 3 4

A triangle similar to given ΔABCwith sides equal to 34 of the sides of ΔABC is

Question

A triangle similar to given

Δ A B C

with sides equal to

\frac{3}{4}

of the sides of

Δ A B C

is constructed.

\frac{B C^{'}}{B C}

is equal to____.

Options:

A . BA′CA′

B . BA′BA

C . BCAC

D . BC′B3C′

Answer: Option B
:
B
As

Δ A B C \sim Δ A^{'} B C^{'}

\frac{B C^{'}}{B C} = \frac{B A^{'}}{B A} = \frac{A^{'} C^{'}}{A C} = \frac{3}{4}
