Dilations Quiz

Draw the image of triangle ABC after a dilation with center (0, 0) and scale factor 1/4. Find the coordinates of each point in the original figure: A, B, and C. Then, multiply each coordinate by 1/4 to find the coordinates of each point in the image: A', B', and C'. Finally, graph the image.
