Question

Match the figures on left side with their corresponding scale factors.

• A. 1
• B. 2
• C. 1.5

Answer 1

Figure 1:


Length of AB = 3 units.
And, length of A'B' = 4.5 units.

$\text{So, Scale factor}=\frac{4.5}{3}=1.5$


Figure 2:


Length of AB = 3 units.
And, length of A'B' = 3 units.

$\text{So, Scale factor}=\frac{3}{3}=1$

Figure 3:


Length of AB = 3 units.
And, length of A'B' = 6 units.

$\text{So, Scale factor}=\frac{6}{3}=2$
