Questions and Answers

In transformational geometry, what does a reflection do to a figure?

  • Rotates the figure around a point
  • Stretches the figure horizontally
  • Flips the figure over a line (correct)
  • Compresses the figure vertically

    • What is the result of reflecting a triangle over the x-axis?

  • The triangle becomes larger
  • The triangle remains unchanged
  • The triangle flips upside down (correct)
  • The triangle shifts to the right

    • If a figure is reflected over the y-axis, what happens to its x-coordinates?

  • They switch places with the y-coordinates
  • They double in value
  • They remain unchanged
  • They become negative (correct)

    • Match the following transformational geometry terms with their definitions:
