b. An isometry preserves shape.
c. An isometry is also rigid motion.
d. All of the above

Answer 1

Answer: a. An isometry preserves distance.

Answer 2

a. An isometry preserves distance.

Explanation:

• An isometry is defined as a distance-preserving transformation. It is also a linear transformation that preserves length.
• Isometries include rotation, translation, reflection, glides, and the identity map.
