Describe the relationship between a ratio and a proportion. Give an example of each.

ΔABC has vertices A(3, -3), B(3, 6), and C(15, 6). Find the ratio of the area of the image to the area of the original figure. How does this ratio compare to the scale factor?

ΔABC has vertices A(3, -3), B(3, 6), and C(15, 6). Find the ratio of the perimeter of the image to the perimeter of the original figure. How does this ratio compare to the scale factor?

ΔABC has vertices A(3, -3), B(3, 6), and C(15, 6). Draw a dilation of ΔABC using a scale factor of 2/3.
