Question

if $k = 1$, the image is ______.
\bigcirc enlarged
\bigcirc shrunk
\bigcirc congruent

Explanation:

In a dilation transformation, the scale factor \( k \) determines the size of the image relative to the original. If \( k = 1 \), the image has the same size and shape as the original, meaning they are congruent. An enlarged image would have \( k>1 \), and a shrunk image would have \( 0 < k < 1 \).

Answer:

C. congruent
