Arotation is an isometry that moves a plane about a fixed point.

The given statement is true.

Step-by-step explanation:

A rotation is an isometry that moves a plane about a fixed point.

Yes this is true.

Isometry is defined as the process of moving an object from one place to another, without changing its size or shape. The various types of isometry are: translation, reflection, rotation, and glide reflection

A rotational isometry is the movement when one point is fixed and all other points moves about a certain angle relative to the fixed point. Here, the angles changes but the shape and size of the object remains same.

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
