14.5: Perform Composite Transformations
5
Two parallel lines are \(8\) units apart. A preimage is reflected over the first line, and then its image is reflected over the next line.

The single transformation that maps the preimage to the final image is a
(translation/reflection/rotation).

The preimage and the final image are units apart.

  • Two reflections over parallel lines that are \(h\) units apart is the same as a single translation of \(2h\) units.
  • \(h = 8\) since the parallel lines are \(8\) units apart.
6
Two parallel lines are \(4.5\) units apart. A preimage is reflected over the first line, and then its image is reflected over the next line.

The single transformation that maps the preimage to the final image is a
(translation/reflection/rotation).

The preimage and the final image are units apart.

  • Two reflections over parallel lines that are \(h\) units apart is the same as a single translation of \(2h\) units.
  • \(h = 4.5\) since the parallel lines are \(4.5\) units apart.
