1. 3d: Perform transformations (rigid and non-rigid motions) on two-dimensional figures using the coordinate plane (DOK 2) By: Deia Sanders

2. Experiment

3. Vocabulary Transformation: a transformation is a translation (sometimes called a slide), a reflection (sometimes called a flip), a rotation (sometimes called a turn), or a dilation (sometimes called an enlargement or reduction) Translation: a translation is the figure resulting from moving every point of a given figure a certain distance in a certain direction

4. More Vocabulary Reflection: a figure is said to be reflected with respect to a line if a fold on the line makes the two figures coincide Rotation: a translation that moves the figure in a clockwise or counterclockwise direction with respect to a specific point Dilation: enlargement or reduction in the polygon; the polygons are similar

5. Let’s look at some examples! Turn to pages 180- 184

7. Reflect 5 places to the right and 2 places down.

10. Label the coordinates of each vertex

11. Sketch the translation across the x-axis (slide, not reflect). Label the coordinates and vertices.

12. Translate your initial 4 units to the left and 2 units up. Label the coordinates and vertices.
