Q2, W4: November 30 – December 4 Pre-Algebra

MAFS.8.G.1.1: Verify experimental properties of rotations, reflections and translations:  Lines are taken to lines, and line segments to line segments of the same length;  Angles are taken to angles of the same measure;  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.

• 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. 
• 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, 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.
