**Tuesday, February 18, 2015**__Common Core Standards__

****Understand congruence and similarity using physical models, transparencies and geometry software.****

8.GA.1 Verify experimentally the properties of rotations, reflections, and translations:

8.GA.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.

8.GA.3 Describe the effect of dilations, translations, rotations, and reflections on two-dimensional figures using coordinates.

8.GA. 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.

Extended Standards: G.68.10a through G.68.12c

Student Objectives

Student Objectives

I can I can identify translations, rotations, dilations, and reflections.

I can translate, rotate, dilate, and reflect given images.

I can explain that translations, rotations, and reflections produce congruent figures, and dilations produce similar figures.
