Answer:

The answer is the "center of rotation."

Step-by-step explanation:

The center of rotation is the point at which an image is rotated to create a second image. That is what has occurred here at point D, therefore it is the center of rotation.

I hope this helps! ☺

When a shape is rotated, it must be rotated through a point.

Point D is the center of rotation

From the diagram, we have:

  • Triangle ABC
  • Triangle A'B'C'
  • Point D

Notice that the triangles are located at either sides of point D

A general rule of rotation is that

The image and the pre-image of the shape that is being rotated will be at the either sides of the center of rotation.

Hence. point D represents the center of rotation.
