Question

Choose all sequences of transformations that produce the same image of a given figure.

a reflection across the y-axis followed by a clockwise rotation 90° about the origin
a reflection across the y-axis followed by a counter-clockwise rotation 90° about the origin
a clockwise rotation 90° about the origin followed by a reflection across the x-axis
a counter-clockwise rotation 90° about the origin followed by a reflection across the y-axis
a reflection across the x-axis followed by a counter-clockwise rotation 90° about the origin

Answer 1

a b

Explanation:

Answer 2

All of these transformations are equivalent to reflection across the line y=x:

A. a reflection across the y-axis followed by a clockwise rotation 90° about the origin

C. a clockwise rotation 90° about the origin followed by a reflection across the x-axis

D. a counter-clockwise rotation 90° about the origin followed by a reflection across the y-axis

E. a reflection across the x-axis followed by a counter-clockwise rotation 90° about the origin
