Which of the following is NOT a rigid motion?

• Rotation

• Reflection

• Translation

• Dilation

Does the transformation appear to be a rigid motion?

• Yes, distances are preserved.

• Yes, angle measures are preserved.

• Yes, both distances and angle measures are preserved.

• No, distances are not preserved.

Which transformations are rigid motion transformations?

• Translations

• Rotations

• Reflections

• Dilations

• Depends on the situation if a transformation is done with rigid motion

• A

• B

• C

• D

A transformation that preserves the size and shape of the figure (translation, reflection, rotation) is called _______________________.

Does the transformation appear to be a rigid motion?

• Yes, it preserves the distance between corresponding points.

• No, it does not preserve the distance between corresponding points.

Two transformations of quadrilateral ABCD are shown below. Identify which transformation is a rigid motion and describe that rigid motion. ​ (a)   is/are a rigid transformation because ABCD maps onto A′B′C′D′ with ​ (b)  

• Only Transformation 2

• Only Transformation 1

• Both Transformation 1 and Transformation 2

• rotation of 60 degrees about point P

• reflection across line that passes through point P

• translation that maps point D to point P
