Make a point in the center of the circular grid. This point will serve as the center of dilation.
Make a point labeled A as shown.
Make a point labeled B as shown.
Make a point labeled C as shown.
Perform a dilation of Point A using a scale factor of 2. Label new point A’.
Perform a dilation of Point B using a scale factor of ½. Label new point B’.
Perform a dilation of Point C using a scale factor of 3. Label new point C’. B C’ B’ C
How would you describe the distance of each point from the center of dilation? A A’
