A dilation centered at the origin always keeps the image on the same side of the coordinate plane as the pre-image.

True

False

Answer explanation

True. A dilation centered at the origin scales distances from the origin, maintaining the relative position of points. Thus, the image remains on the same side of the coordinate plane as the pre-image.
