Question

1. tell whether each transformation is a rigid motion or is not a rigid motion.

this is
because the size and shape do
not change.
this is
because
the size changes.

Explanation:

Step1: Recall the definition of rigid motion

Rigid motion is a transformation that preserves the size and shape of a figure.

Step2: Analyze the first transformation

The first transformation has no change in size and shape. So it is a rigid motion.

Step3: Analyze the second transformation

The second transformation has a change in size. So it is not a rigid motion.

Answer:

The first transformation is a rigid motion. The second transformation is not a rigid motion.
