Question

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

Select all that apply.

a translation 2 units up followed by a rotation of 180° about the origin

a dilation with a scale factor of 2 followed by a reflection across the x-axis

a reflection across the y-axis followed by a dilation with a scale factor of 0.5

a rotation about the origin of 25° followed by a reflection across the y-axis

Answer 1

If the transformation will result to an after-image that not is congruent to the original figure, then the transformation is most probably a dilation. Amon the choices, the answer must be
a reflection across the y-axis followed by a dilation with a scale factor of 0.5
