Question

the triangle ( tuv ) is a dilation of the triangle ( tuv ). what is the scale factor of the dilation?
simplify your answer and write it as a proper fraction, an improper fraction, or a whole number.

Explanation:

Step1: Identify coordinates of U and U'

From the grid: $U(0,3)$, $U'(0,1.5)$

Step2: Calculate scale factor

Scale factor = $\frac{U'y-coordinate}{Uy-coordinate} = \frac{1.5}{3} = \frac{1}{2}$

Answer:

$\frac{1}{2}$
