How can you tell the image from the pre-image?

• The image is called "prime". It has a tick mark next to the letter.

• The pre-image is called "prime". It has a tick mark next to the letter.

• The image is called "prime". It always uses a different letter

• You can just tell

Congruent means...

• Two shapes that are the same exact size

• Shapes that look the same

• Shapes with the same number of sides

• Two similar shapes
