Dilations Exploration

When the image A'B'C'D' is [b]larger[/b] than the original figure ABCD (the preimage), the dilation is called an enlargement. [b]What is the scale factor for enlargements?[/b]
When the image A'B'C'D' is [b]smaller[/b] than the original figure ABCD (the preimage), the dilation is called a reduction. [b]What is the scale factor for reductions?[/b]
What is the [b]center of dilation[/b] on this graph?
Set the [b]scale factor to 2[/b]. The ordered pairs of the preimage are A (2, 2), B (6, 2), C (5, 4), and D (3, 4). [br]What are the ordered pairs of the image A'B'C'D'? [b]How are those ordered pairs related to the scale factor?[/b]
Now [b]set the scale factor to 0.5[/b]. How are the coordinates of the ordered pairs of the image A'B'C'D' related to the original points this time?
[b]Note:[/b] Using the scale factor in this way to find the coordinates of image points works when the center of dilation is the [u]origin[/u] (0, 0).
Is a dilation an [b]isometry[/b]?
With dilations, are the image and preimage [b]similar figures[/b]?
