Exploring Sequencing Rigid Motions in Eureka Math

This lesson covers sequences of rigid motions, focusing on translation, reflection, and rotation. Students review these concepts and learn to describe transformations with precision, identifying the type and rule followed. The lesson includes practice exercises and instructions for independent work, preparing students for their mid-module assessment.

What is a rigid motion?

• A transformation that keeps size and shape constant

• A transformation that changes size and shape

• A transformation that only changes size

• A transformation that only changes shape

Which of the following is NOT a type of rigid motion?

• Reflection

• Translation

• Dilation

• Rotation

When describing a transformation, what are the two parts you need to include?

• Type of transformation and the rule followed

• Type of transformation and the color used

• Rule followed and the time taken

• Type of transformation and the size of the object

What is the rule for a translation?

• Using a line of reflection

• Using a scale factor

• Using a vector

• Using a point and degrees

In the example where triangle ABC is transformed to triangle A'B'C', what type of transformation was used if it involved a flip?

• Reflection

• Dilation

• Rotation

• Translation

If a triangle is rotated around point B, what stays in the same spot?

• Point A

• Point B

• Point C

• All points move

In a sequence of rigid motions, what is the first step if you need to flip and then spin a triangle?

• Translation

• Rotation

• Reflection

• Dilation

What is the correct sequence of transformations if you first slide, then spin, and finally flip a triangle?

• Rotation, Reflection, Translation

• Translation, Rotation, Reflection

• Reflection, Translation, Rotation

• Translation, Reflection, Rotation

What should you do if you are unsure about the transformations needed to map one figure onto another?

• Skip the problem

• Ask a friend for the answer

• Use a transparency to experiment

• Guess the transformations

What is the final step in the independent practice instructions?

• Review the lesson again

• Complete the exit ticket and turn it in

• Check your answers online

• Complete the problem set
