Lesson 1.13
Warm-Up: Left to Right
Work Session 1: Turning on a Grid
Please use the Geogebra applet below to complete the rigid transformations:
- Rotate ABCD 90 degrees clockwise around Q.
- Rotate ABCD 180 degrees around R.
Work Session 1: Turning on a Grid
Please use the Geogebra applet below to complete the rigid transformations:
- Rotate HJKLMN 120 degrees clockwise around O.
- Rotate HJKLMN 60 degrees counterclockwise around P.
Work Session 2: Translate, Rotate, Reflect
Mai suspects triangle ABC is congruent to triangle DEF. She thinks these steps will work to show there is a rigid transformation from ABC to DEF.
- Translate by directed line segment v.
- Rotate the image ____ degrees counterclockwise around point D.
- Reflect that image over line DE.
Summary
Cool Down: Find a Sequence
Cool Down: Find a Sequence
Describe a sequence of reflections, rotations, and translations that takes ABCD onto A’B’C’D’. You can do the transformations in the drawing above, or you can describe the transformations here.
