Directions:

Let's figure out if there is a sequence of transformations that maps one figure onto another.

First, you'll have 4 minutes of quiet work time.
We will share our responses as a class.

1a. Which one?

Here is a grid showing triangle ABC and two other triangles.You can use a rigid transformation to take triangle ABC to one of the other triangles. Which one?

Jelöld be válaszodat

A
Triangle BDE
B
Triangle CFG

Check my answer (3)

1b. Which one?

Describe a rigid transformation that takes ABC to the triangle you selected.

2. Use what you know about rigid transformations to justify your response.

Can triangle ABC be taken to triangle DBE? Why or why not?

For the next three questions, use the app to determine your answer.

Be prepared to share your reasoning during a class discussion. For example, for a rotation, you should specify the center of rotation, the direction, and the angle of rotation.

3. Can triangle ABC be taken to triangle CFG with only a translation?"
