Question

This diagram shows a pre-image A ABC, and its image,

AA"B" C", after a series of transformations.
Select from the drop-down menus to correctly complete the

to become
A A"B" C". Because the transformations are

the pre-image and image are
Choose...

Answer 1

ABC is rotated 90 degrees clockwise to become A'B'C'

A'B'C' is rotated 180 degrees clockwise to become A"B"C"

Answer 2

ABC is reflected across the y-axis to become △A′B′C′. Then ​△A′B′C′​ is rotated 90 degrees counterclockwise about the origin to become ​△A′′B′′C′′​ . Because the transformations are both rigid, the pre-image and image are congruent.
