MAFS.8.G.1.1

Verify experimental properties of rotations, reflections and translations:

  1. Lines are taken to lines, and line segments to line segments of the same length.
  2. Angles are taken to angles of the same measure.
  3. Parallel lines are taken to parallel lines.

MAFS.8.G.1.2

Understand that a two-dimensional figure is congruent to another if the second can be obtained from the first by a sequence of rotations, reflections, and translations; given two congruent figures, describe a sequence that exhibits the congruence between them.

MAFS.8.G.1.3

Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates.

MAFS.8.G.1.4

Understand that a two-dimensional figure is similar to another if the second can be obtained from the first by a sequence of rotations, reflections, translations, and dilations; given two similar two-dimensional figures, describe a sequence that exhibits the similarity between them.

Learning Targets and Learning Criteria

Students are successful when they can:

  • explain how transformations can be used to prove that two figures are similar.
  • describe a sequence of transformations to prove or disprove that two given figures are similar.
  • know the definition of similar and why dilation alone is not enough to determine similarity.
  • describe changes occurring to x- and y-coordinates of a figure after a translation, reflection, rotation, or dilation.
  • reason that a 2-D figure is congruent to another if the second can be obtained by a sequence of rotations, reflections, translation.
  • describe the sequence of rotations, reflections, translations that exhibits the congruence between 2-D figures using words.
  • describe a sequence of rigid motions to map one figure onto another.
  • explain how transformations can be used to prove two figures are congruent.
  • perform a series of transformations (reflections, rotations, and/or translations) to prove or disprove that two given figures are congruent.
  • describe a sequence of rigid motions to map one figure onto another.
  • describe and apply the properties of translations, rotations, and reflections on lines, line segments, angles, parallel lines and geometric figures.
