1. what is the result of rotating a shape 90 degrees around a fixed point?

a. the shape becomes a mirror image
b. the shape is reflected over an axis
c. the shape changes orientation but not size
d. the shape changes size

Explanation:

A 90-degree rotation around a fixed point is a rigid transformation, which preserves the size and shape of the original figure. It only changes the orientation of the shape. A mirror image/axis reflection is a different transformation, and size change occurs in dilations, not rotations.

Answer:

c. The shape changes orientation but not size
