A double reflection of a preimage across perpendicular lines produce the same result as a:

Question

A. scaled dilation
B. 180-degree rotation
C. 90-degree rotation
D. 270-degree rotation

Answer 1

A double reflection of a preimage across two perpendicular lines is equivalent to a 180-degree rotation. This occurs because the reflection across one line followed by reflection across another line that is perpendicular to the first results in a rotation of the original figure around the point where the two lines intersect.

Thus, the correct answer is: B. 180-degree rotation.
