Lesson 10 focuses on sequences of rigid motions, including translation, rotation, and reflection. The lesson provides detailed examples and exercises to illustrate how these transformations can be combined to map geometric figures. Emphasis is placed on using precise language to describe the transformations and understanding the impact of the order of operations. The lesson concludes with a recap of key concepts and preparation for the mid-module assessment.

What are the three types of rigid motions discussed in the lesson?

• Reflections, Scaling, Translations

• Reflections, Translations, Rotations

• Scaling, Shearing, Rotations

• Translations, Shearing, Reflections

Why is the order of transformations important in a sequence?

• It has no effect on the final outcome.

• It determines the final position of the figure.

• It affects the color of the figure.

• It changes the size of the figure.

In the first exercise, which rigid motion maps triangle ABC onto triangle A'B'C'?

• Rotation

• Reflection

• Scaling

• Translation

What additional detail is needed when describing a rotation?

• The speed of rotation

• The color of the figure

• The center and degrees of rotation

• The size of the figure

In the advanced exercises, what is the first step to map one triangle onto another?

• Reflection

• Rotation

• Translation

• Scaling

What is the purpose of using a transparency in these exercises?

• To speed up the process

• To change the color of the figure

• To increase the size of the figure

• To prove the mapping of figures

In the final example, what is the first transformation applied to map figure ABC onto A'B'C'?

• Translation

• Reflection

• Rotation

• Scaling

What is the final step in mapping the complex figures in the last example?

• Translation

• Scaling

• Rotation

• Reflection

Why is it important to describe the sequence of transformations accurately?

• To make the process faster

• To ensure the correct mapping of figures

• To change the color of the figures

• To increase the size of the figures

What should be specified when describing a reflection?

• The speed of reflection

• The size of the figure

• The color of the line

• The line of reflection
