Standard(s) Taught

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.1.3

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

Learning Targets and Learning Criteria

Students are successful when they can:

• verify – by measuring and comparing lengths, angle measures, and parallelism of a figure and its image – that after a figure has been translated, reflected, or rotated, corresponding lines and line segments remain the same length, corresponding angles have the same measure, and corresponding parallel lines remain parallel.
• describe and apply the properties of translations, rotations, and reflections on lines, line segments, angles, parallel lines and geometric figures.
• describe the 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, translations.
• 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.
