Question

△MNO is rotated about point A to △M′N′O′ . Which statements are true about the pre-image and image? Select each correct answer.

The image is the same shape but a different size than the pre-image.

The image is the same size but a different shape than the pre-image.

MN ≅ M′N′

Answer 1

The correct option is MN = M'N' since the first two options can be eliminated through the rules of rigid transformations.

Answer 2

MN ≅ M′N′

Explanation:

When you rotate an image on a certain pivot point, you´ll end up with two equal images in shape and form, but with different angles from the center, since the image is the same shape, form and length, their sides and angles should be the same, so the sentece that is true is that MN ≅ M′N′.
