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 . &nbsp B A ′ C A ′ B . &nbsp B A ′ B A C . &nbsp B C A C D . &nbsp B C ′ B 3 C ′

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 .

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

B .

\frac{B A^{'}}{B A}

C .

\frac{B C}{A C}

D .

\frac{B C^{'}}{B_{3} C^{'}}

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}
