Lesson 4
Making the Moves
Let’s draw and describe translations, rotations, and reflections.
Problem 1
For each pair of polygons, describe a sequence of translations, rotations, and reflections that takes Polygon P to Polygon Q.
Problem 2
Here is quadrilateral \(ABCD\) and line \(\ell\).
![Quadrilateral \(A \) \(B\) \(C\) \(D\) and dashed line \(l\) with a positive slope. \(B\) \(C\) is parallel to line \(l\).](https://staging-cms-im.s3.amazonaws.com/w69G4VaZ4wDGKq6Tb8dqthc2?response-content-disposition=inline%3B%20filename%3D%228-8.1.A2.newPP.04.png%22%3B%20filename%2A%3DUTF-8%27%278-8.1.A2.newPP.04.png&response-content-type=image%2Fpng&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIAXQCCIHWF37H2AMFB%2F20240722%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20240722T141528Z&X-Amz-Expires=604800&X-Amz-SignedHeaders=host&X-Amz-Signature=b23b47c00b9e108a7d6ed702175dc610e102906ddff38a66ceb2b59d3b811a80)
Draw the image of quadrilateral \(ABCD\) after reflecting it across line \(\ell\).
Problem 3
Here is quadrilateral \(ABCD\).
![Quadrilateral A B C D. A B, A D and D C all have negative slopes. B C has a positive slope. A B C D has no parallel sides and no right angles.](https://staging-cms-im.s3.amazonaws.com/awLCEPgA3sFPyMqxd2UeEmxz?response-content-disposition=inline%3B%20filename%3D%228-8.1.A2.newPP.02.png%22%3B%20filename%2A%3DUTF-8%27%278-8.1.A2.newPP.02.png&response-content-type=image%2Fpng&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Credential=AKIAXQCCIHWF37H2AMFB%2F20240722%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Date=20240722T141528Z&X-Amz-Expires=604800&X-Amz-SignedHeaders=host&X-Amz-Signature=5c172b498437b20d4dbef5e5900f7c3cf9e3de687328539701df5cfd9cd53db7)
Draw the image of quadrilateral \(ABCD\) after each rotation using \(B\) as center.
- 90 degrees clockwise
- 120 degrees clockwise
- 30 degrees counterclockwise
