Things to Learn

  • Perform translations of figures along a specific vector. Students label the image of the figure using appropriate notation.
  • Realize that a translation maps lines to lines, rays to rays, segments to segments, and angles to angles.
  • Discover that translations preserve lengths of segments and degrees of angles.
