Geometry

Question Analysis:
This question tests knowledge of compositions of transformations and their effects on congruence and orientation.

Key Concept Explanation:
Isometries preserve size and shape.
Reflections change orientation.
Rotations preserve orientation unless preceded by a reflection.

Step-by-Step Solution:
Reflection over the x-axis:
Preserves size but reverses orientation.
90° Counterclockwise Rotation:
Preserves size but does not restore the original orientation.
Since both transformations preserve distance, the overall transformation is an isometry.
However, because the reflection flipped the figure once, the final image does not have the same orientation as the original.

Option Analysis:
A) Incorrect—The transformation does not preserve orientation.
B) Correc...
