Question

Determine whether or not each example is a rigid motion. If yes, identify the type of transformation.

Flipping a pancake
Deflating an air mattress
Moving a clock's minute hand
Enlarging a photo
Putting a golf ball
Looking in a car's rear view mirror

Answer 1

The following examples are examples of rigid motion:

Flipping a pancake - reflection

Moving a Clocks minute hand - rotation

Putting a golf ball - Translation

Looking in a cars rearview mirror - reflection

Answer 2

Transformations - 1, 3, 5, 6

Not Transformations - 2, 4

Explanation:

We know that,

Rigid transformations are of three types - Reflection, Rotation and Translation.

According to the options, we see that,

The situations which are not examples of rigid transformations are:

2. Deflating an air mattress and 4. Enlarging a photo

Then, the transformations which other situations represents are:

1. Flipping a pancake - Reflection

3. Moving a clock's minute hand - Rotation

5. Putting a golf ball - Translation

6. Looking in a car's rear view mirror - Reflection
