Quadrilateral EFGH was dilated by a scale factor of 2 from the center (1, 0) to create E′F′G′H′.

Which characteristic of dilations compares segment E′F′ to segment EF?
A segment that passes through the center of dilation in the pre-image continues to pass through the center of dilation in the image. A segment in the image has the same length as its corresponding segment in the pre-image. A segment that passes through the center of dilation in the pre-image does not pass through the center of dilation in the image. A segment in the image is proportionally longer or shorter than its corresponding segment in the pre-image.
