Question

Triangle JKL is transformed by performing a 90 clockwise rotation about the origin and then a reflection over the y-axis, creating triangle J’’K’’L’’. Which transformation will map J’’K’’L’’ back to JKL?
a reflection over the y-axis and then aclockwise rotation about the origin
a reflection over the x-axis and then a counterclockwise rotation about the origin
a reflection over the x-axis and then a clockwise rotation about the origin
a reflection over the x-axis and then a reflection over the y-axis

Answer 1

Answer:

A reflection over the y-axis and then a counterclockwise rotation by 90° about the origin.

Step-by-step explanation:

Triangle JKL is transformed by performing by 90° clockwise rotation about the origin, creating triangle J'K'L' and then a reflection over the y-axis, creating triangle J’’K’’L’’ (see attached diagram for details).

To map J''K''L'' back to JKL, we need to perform the transformations in inverse order: first, a reflection over the y-axis and then a counterclockwise rotation by 90° about the origin.
