Translations, reflections, rotations, and dilations are transformations. Translations, reflections, and rotations create images that are congruent to the original figures. Their corresponding sides and angles are congruent. The pre-image and the prime image are the exact same size and shape.

Dilations create images that are smaller or larger than the original figures but retain the same shape. The corresponding angles of the original figure and the new image are congruent but their side lengths are proportional not equal.

In elementary school, a translation was called a slide. A reflection was called a flip, and a rotation was called a turn.

Plans carried over from last week

Common Core Standards and Extended Standards

8.G.1 Verify experimentally the 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.

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