## Highlight

What's been the best thing about your week so far?

Use the polygon tool and the "Transform" menu to create a logo below that uses congruent transformation. Click the "More" button to see the "Transform" menu. Don't be afraid to add some color! :)

When you are done with the logo, complete examples 3 and 4 in the notes packet. Then, come back to this when you get to the first page of the 4.1B notes to do the 4 transformations below. :)

Perform the following transformations for each triangle below using the transformation tools:
1.) Reflect

*ABC*over segment BC 2.) Translate*DEF*, using segment DF as your vector to translate across (going from D to F). 3.) Rotate*GHI*180 degrees around point*I*. 4.) Rotate*JKL*180 degrees around the midpoint of segment*KL*. You will need to create the midpoint using the midpoint tool (Points menu). After you have created all 4 triangles, use the angle measure tool and the segment measure tool to measure the angles and sides of all 8 triangles to see which sides and angles match up (aka "correspond") with each other. -When you have finished this, you can do the "Mystery Transformation" below it.## Congruent Triangle Transformations

## Mystery Transformation

Describe the steps of the mystery transformation(s) that map the blue triangle onto the orange triangle. Be specific! :)

## Mystery Transformation

Type your answer below of the steps you took to map the blue triangle onto the orange triangle:

Now that you are done with the Mystery Transformation, you can go back to the 4.1B notes and complete the examples. The Geogebra portion is finished. :)
