Have you ever looked closely at a butterfly and noticed how its two wings look like perfect twins?
When two sides of a shape match each other exactly, we say it has symmetry.
A line of symmetry (or fold line) divides a figure into two matching halves.
For Early Level learners, this is introduced as an imaginary straight line drawn vertically down the middle.
A line of symmetry (or fold line) divides a figure into two matching halves.
For Early Level learners, we explore this as an imaginary straight line drawn vertically down the middle.

This center line acts like a fold line, making the left side match the right side.
Do you think your own face has matching sides too?
