Question

What is the scale factor of the triangle dilated from OPQ to OP’Q’ from center O? Explain and/or show your work

Answer 1

Answer:

The scale factor is $\frac{3}{8}$

Step-by-step explanation:

The scale factor is calculated using the formula

$k=\frac{|P'Q'|}{|PQ|}$

We use the absolute value method to find the corresponding lengths,

Each box is 0.5 units.

$k=\frac{|3.5-2|}{|6-2|}$

$k=\frac{1.5}{4}$

$k=\frac{3}{8}$
