Transformations

If the scale factor is greater than 1, the dilation is...

• an enlargement
• a rotation
• a translation
• a reduction

Enlargement or reduction?  Find the scale factor!

• It's a reduction; the scale factor is 2.
• It's an enlargement; the scale factor is 2.
• It's an enlargement; the scale factor is 1/2.
• It's a reduction; the scale factor is 1/2.
