What is a Dilation?
Pg

A stretch!
Think of Ant Man!
Is a dilation a rigid motion?Slide3
If the scale factor is
<
1
, the dilation is called a reduction.If the scale factor is
> 1, the dilation is called an enlargement.
What are the scale factors for
each of these dilations?

Diameter of the moon is about 2200 mi.
2.2 cm
When looking through a telescope, an astronomer
measures the diameter of the moon to be 2.2 cm.
He knows that the telescope shows 1000 miles
in each centimeter.
What is the scale factor?
