|Subject Area||8th Grade Math (Pre-Algebra)|
|Unit of Instruction||Focus 6 – Transformations|
MAFS.8.G.1.1: Verify experimental properties of rotations, reflections and translations: a. Lines are taken to lines, and line segments to line segments of the same length. b. Angles are taken to angles of the same measure. c. 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.
|Learning Targets and Learning Criteria|
• 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. (side, shape and orientation)
• explain how transformations can be used to prove that 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.
