In the picture
- The crease running down the middle of the paper
- The big orange spot on the left wing
- The matching orange spot on the right wing
Examples
- A paper heart cut from a folded sheet has two halves that match.
- A butterfly resting on a flower has the same pattern on both wings.
Key takeaways
- A fold line that makes two matching halves is called a line of symmetry.
- If the halves do not land on top of each other, the shape is not symmetrical there.
