Question

unit 3 lesson 1 cumulative practice problems 1. decide if the scale factor is greater than one or less than one in each dilation. explain how
eduction or enlargement then identify the scale factor

Explanation:

Step1: Analyze Dilation Direction

Check if the image is larger (enlargement) or smaller (reduction) than the original. If the image is larger, scale factor \( k > 1 \); if smaller, \( k < 1 \).

Step2: Determine Scale Factor Magnitude

From the diagram (assuming the larger triangle is the image), since the image is bigger than the original, the scale factor is greater than 1. If the image were smaller, it would be less than 1.

Answer:

If the dilated figure (image) is larger than the original, the scale factor is greater than 1; if smaller, less than 1. (Example: If the image is an enlargement, scale factor \( > 1 \); if reduction, \( < 1 \).)
