Question Analysis
The main focus is to determine the type of dilation based on the scale factor .
Key Concept Explanation
Enlargement: Occurs when the scale factor k > 1, making the dilated figure larger than the original.
Reduction: Occurs when 0 < k < 1, making the dilated figure smaller.
Isometry: Preserves distance (e.g., translations, rotations), which does not apply to dilation (unless k = 1).
