Final answer:
The transformation that results from rotating a shape 270° clockwise about a point is rotation.
Step-by-step explanation:
The transformation that results from rotating a shape 270° clockwise about a point is c) Rotation.
Rotation is a transformation that turns a shape around a fixed point or axis. In this case, the shape is rotated 270° clockwise, meaning it turns in the direction opposite to the hands of a clock by an angle of 270°. This type of rotation preserves the shape and size of the original shape.
