Answer: A rotation is an isometry that movesa plane about a fixed point.
Explanation:
- A linear transformation of a plane that preserves length is known as isometry.
- A rotation transformation is a rigid transformation or isometery which create the image of a figure ( called as pre-image) with same shape and size by rotating it by some degrees about the fixed center of rotation.
Hence, A rotation is an isometry that moves a plane about a fixed point.
