2. A dilation is when the figure either gets larger (enlargement) or smaller (reduction). =

3. A translation is when a figure moves right, left or up & down on the coordinate grid.

4. Enlargement- When the figures original dimensions enlarge. ( Get bigger ) Reduction- When the figures original dimensions reduce. ( Get smaller)

5. A reflection is when it flips over the x or y axis. It’s like a mirror image.

6.  Scale factor is what you multiply by to get from your original figure to the new figure.  The scale factor is great than 1 if it is a enlargement.  The scale factor is less than 1 if it is reduction.

7. TThe perimeter is affected the same way as the scale factor. If the scale factor is 3 the perimeter will be 3 times the size of the original figure.

8. To find the change of the area you find the area of both figures and divide the new area by the original area.
