Classwork Example 1 So far we have seen how to sequence translations, sequence reflections, and sequence translations and reflections. Examples of Student Work at this Level The student: Can you identify a rigid motion or sequence of rigid motions that will map onto Can you identify one transformation that would be needed to map onto?

In the following picture, we have two pairs of triangles. Can you explain this in terms of rigid motion? Is it possible to identify both the center and the degree of rotation?

Show Step-by-step Solutions Composition of Rigid Motions This video shows how we can move geometric figures around the plane by sequencing a combination of translations, reflections and rotations.

Consequently, it is important to explicitly state when vertices are mapped onto corresponding vertices by a transformation and to provide a justification for these occurrences. Provide the student with two congruent figures e. You can use the free Mathway calculator and problem solver below to practice Algebra or other math topics.

Does it make a difference? What does 6, 5 represent? Questions Eliciting Thinking Can you describe in more detail how this sequence of rigid motions will map one triangle onto the other? Represents the number of units in which the figure is translated as an ordered pair [e.

Encourage the student to be precise when describing translations. Pair the student with a Got It partner and have the students compare their descriptions and reconcile any differences.

Show the student the conventional ways to describe a translation e. Next provide two congruent figures that are related by more than one rigid motion.

What happened after the translation? The student is unable to accurately describe a rigid motion that demonstrates congruence.

Writes that the figures are congruent because they look the same. Can you define the word congruence in terms of rigid motion? We start with two identical figures. How do you know? Once the student has successfully identified a sequence of rigid motions, assist the student in describing the sequence using correct terminology and notation.

Does not include detailed descriptions of the translation and rotation. Show Step-by-step Solutions Rotate to landscape screen format on a mobile phone or small tablet to use the Mathway widget, a free math problem solver that answers your questions with step-by-step explanations.

Provide the student with several other examples of congruent triangles shown on the coordinate plane. Then make clear that the figures are congruent because the translation carries one figure onto the other. What sequence of basic rigid motions maps the left H exactly onto the right H so that all corresponding angles and segments coincide?

Got It The student provides complete and correct responses to all components of the task.

Can you explain in more detail how this sequence of rigid motions maps onto How will performing a rigid motion affect the size and shape of?

Ask the student to use the transparency to model a sequence of rigid motions that maps onto providing assistance as needed. Did any of the sides coincide? Ask the student to describe the coordinates of the vertices of the image after each rigid motion. Questions Eliciting Thinking Can you describe the translation more specifically?

Explain that two figures are congruent if there is a sequence of rigid motions that carries one figure onto the other. Can you correct your error?Chapter 09 Test Use the figures below. Write a sequence of rigid motions that maps RSTto DEF. (DEF) (DEF) = (DEF) Use the figures below.

Write a sequence of rigid motions that maps AB to Y. MAFSG-CO Use the definition of congruence in terms of rigid motions to show that two triangles are congruent if and only if corresponding pairs of sides and corresponding pairs of angles are congruent.

Write a sequence of rigid motions that maps ab to xy, please for the love of God don't answer if you don't know it, you will be reported/5(7).

you write the reflection across m that takes P to P' as Rm(P)=P' a figure has symmetry if there is a rigid motion that maps the figure onto itself. line symmetry. two figures are congruent if and only if there is a sequence of one or more rigid motions that maps one figure onto another.

Rigid Motions and Congruent Triangles - Independent Practice Worksheet Complete all the problems. Make sure to draw pictures to help you solve the problems. distance, there is no sequence of rigid motions that will map ∆.

Students describe a sequence of rigid motions that maps one figure onto another. Classwork Example 1 (8 minutes) So far, we have seen how to sequence translations, sequence reflections, sequence translations and reflections, and Lesson Sequences of Rigid Motions.
