An artist creates the basic pattern for a tablecloth by creating two similar triangles, AABC and AABC , in the coordinate plane. • The vertices of AABC are A(1, 2) , B(1, 3) , and C(3, 2). • The vertices of AA BC are A (3, – 6), B (3, – 9), and C (9, – 6) . Which of these could be a sequence of two transformations that maps AABC to AA BC ? Choose all that are correct. Dilation by a factor of 3 about the origin, followed by reflection across the a -axis. A. B. Reflection across the r -axis, followed by dilation by a factor of 3 about the origin. C. Dilation by a factor of 3 about the origin, followed by reflection across the y -axis. Reflection across the y -axis, followed by dilation by a factor of 3 about the origin. D. Dilation by a factor of -3 about the origin, followed by reflection across the y -axis. E. Reflection across the z -axis, followed by dilation by a factor of -3 about the origin. F.
