If you apply the geometric description of reflections across parallel lines, what transformation can you predict will be part of a composition transformation?

Question

A. a translation
B. a reflection
C. a dilation
D. a rotation

Answer 1

When reflecting a figure across two parallel lines, the overall transformation can be described as a translation. The reason for this is that reflecting a point across the first line and then across the second line results in the point being moved along the line that is perpendicular to the parallel lines by a distance that is twice the distance from the point to the first line.

Thus, the correct answer is:

A. a translation
