1. TARA HUTCHENS 8 TH GRADE PRE-ALGEBRA APRIL 9, 2015 CCSS 8.G.3 Symmetry and Transformations

2. Transformation Movement of an original geometric shape to another according to a predefined rule

3. Reflection Each point of the figure’s image is the same distance from the line of reflection as the corresponding point of the preimage. Try it Out!

4. Translation A reflection through a pair of parallel lines. Try it Out!

5. Rotation Reflecting a figure through each of two intersecting lines in succession. Try it Out!

6. Symmetry Line- each half of the figure is a reflection of the other half. Rotational- during a rotation of less than 360  around a center point, the image coincides with the original figure. Point- 180  rotational symmetry.

7. Symmetry- What does it look like? Line Rotational
