Transformations

Which of the following is an acceptable explanation why transformed figures are congruent to the original figures.

• The figures are actually NOT congruent.
• It depends on whether you translated, rotated, or reflected.
• Side lengths and angles measures stay the same when transformed.
• The figures look the same.

Which of the following describes the sequence of transformations shown?

• Reflect across the x-axis and then rotate -90 degrees around the origin
• Rotate -90 degrees around the origin and then translate down.
• Reflect across the x-axis and then reflect across the y-axis.
• Translate up and then rotate 90 degrees about the origin.
