If the scale factor is less than one, the new figure will be

• an enlargement
• a reduction
• a scale factor
• bigger

If the scale factor is greater than one, the new figure will be

• a reduction
• an enlargement
• a scale
• not proportional

If a Scale Factor if greater than 1, then your figure gets...

• Smaller
• Bigger
• Does not change
