Question

polygon t is a scaled copy of polygon s. what scale factor takes polygon s to polygon t?

Explanation:

Step1: Select corresponding sides

We can use the pair of sides 50 in polygon S and 20 in polygon T.

Step2: Calculate scale - factor

The scale factor $k$ from polygon S to polygon T is found by dividing the length of the side in polygon T by the length of the corresponding side in polygon S. So $k=\frac{20}{50}$.

Step3: Simplify the fraction

$\frac{20}{50}=\frac{2}{5}=0.4$.

Answer:

$0.4$
