Question

triangle qrs was dilated using the dilation rule ( d_{p,4} ). what is ( pr )?
options: 6 units, 9 units, 12 units, 15 units

Explanation:

Step1: Identify dilation center and scale factor

Dilation rule is $D_{P,4}$, so center is $P$, scale factor $k=4$.

Step2: Find length of $PR$

From the graph, $PR = 3$ units.

Step3: Calculate $PR'$

$PR' = k \times PR = 4 \times 3 = 12$ units.

Answer:

C. 12 units
