Which sequence of transformations would result in a figure that is similar, but not congruent, to the original figure?

Select all that apply.

A. a dilation with a scale factor of 1.9 followed by a rotation of - 30°

B. a dilation with a scale factor of 0.1 followed by a translation of 5 units left

C. a reflection across the y-axis followed by a dilation with a scale factor of 10

D. a rotation about the origin of 65° followed by a reflection across the x-axis
