Which of the following is true about the image and pre-image in a reflection?

• The image is a different shape from the pre-image in a reflection.

• The image is the result of the reflection transformation, while the pre-image is the original shape before the reflection.

• The image is the original shape before the reflection, while the pre-image is the result of the reflection transformation.

• The image and pre-image are the same in a reflection.

Which of the following is true about the distance between a point and its reflection?

• The distance is three times the distance between the point and the line of reflection.

• The distance is half the distance between the point and the line of reflection.

• Twice the distance between the point and the line of reflection.

• The distance is equal to the distance between the point and the line of reflection.
