### 3d transformations

1. 1. 3d: Perform transformations (rigid and non-rigid motions) on two-dimensional figures using the coordinate plane (DOK 2)<br />By: Deia Sanders<br />
2. 2. Experiment<br />
3. 3. Vocabulary<br />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)<br />Translation: a translation is the figure resulting from moving every point of a given figure a certain distance in a certain direction<br />
4. 4. More Vocabulary<br />Reflection: a figure is said to be reflected with respect to a line if a fold on the line makes the two figures coincide<br />Rotation: a translation that moves the figure in a clockwise or counterclockwise direction with respect to a specific point<br />Dilation: enlargement or reduction in the polygon; the polygons are similar<br />
5. 5. Let’s look at some examples!<br />Turn to pages 180- 184<br />
6. 6. Turn to Handout #1<br /><ul><li>Draw a figure in quadrant 2
7. 7. Reflect 5 places to the right and 2 places down.
8. 8. Rotate it 90 degrees clockwise</li></li></ul><li>Day 2<br />3d: Perform transformations (rigid and non-rigid motions) on two-dimensional figures using the coordinate plane (DOK 2)<br />
9. 9. Turn to Handout #1 <br /><ul><li> Draw your first initial in block letters in quadrant I
10. 10. Label the coordinates of each vertex
11. 11. Sketch the translation across the x-axis (slide, not reflect). Label the coordinates and vertices.
12. 12. Translate your initial 4 units to the left and 2 units up. Label the coordinates and vertices.
13. 13. Check your neighbors work</li></li></ul><li>Classwork<br />Complete Handout #2 <br />page 196<br />(you may want to use remaining graphs in Handout #1 to complete)<br />
14. 14. Day 3<br />3d: Perform transformations (rigid and non-rigid motions) on two-dimensional figures using the coordinate plane (DOK 2)<br />
15. 15. Let’s Review Vocabulary<br />Transformation<br />Translation<br />Reflection<br />Rotation<br />Dilation<br />
16. 16. Review <br />Please get out last nights homework and exchange papers<br />
17. 17. Classwork<br />Complete Handout #3 <br />Pages 198-199<br />
18. 18. Practice Problems<br />Review for test tomorrow<br />
