12.5. Composition of Transformations http://www.ck12.org
- Perform a glide reflection over they−axis and down 5 units. Write the new coordinates.
- What is the rule for this glide reflection?
- What glide reflection would move the image back to the preimage?
Use the graph of the triangle below to answer questions 11-15.
- Reflect the preimage overy=−1 followed byy=−7. Write the new coordinates.
- What one transformation is this double reflection the same as?
- What one translation would move the image back to the preimage?
- Start over. Reflect the preimage overy=−7, theny=−1. How is this different from #11?
- Write the rules for #11 and #14. How do they differ?
Use the graph of the trapezoid below to answer questions 16-20.
