kim performed a transformation on rectangle abcd to create rectangle a'b'c'd', as shown in the figure below:

what transformation did kim perform to create rectangle a'b'c'd'?

rotation of 270 degrees counterclockwise about the origin
reflection across the line of symmetry of the figure
reflection across the y‐axis
rotation of 90 degrees counterclockwise about the origin

Which statement accurately explains whether a reflection over the y-axis and a 270° counterclockwise rotation would map figure acb onto itself? a coordinate plane with figure acb with point a at 1, 1, c at 3, 4 and b at 5, 1 yes, a″c″b″ is located at a″(1, 1), c″(4, 3), and b″(1, 5) yes, a″c″b′ is located at a″(1, 1), c″(3, 4), and b″(5, 1) no, a″c″b″ is located at a″(1, 1), c″(4, 3), and b″(1, 5) no, a″c″b″ is located at a″(1, 1), c″(3, 4), and b″(5, 1)

Find the power set of each of these sets, where a and b are distinct elements. a) {a} b) {a, b} c) {1, 2, 3, 4} show steps
