LINES OF SYMMETRY

A line of symmetry divides a shape into two identical halves that are mirror images of each other. If you fold along the line, both sides match perfectly. A square has 4 lines of symmetry, a rectangle has 2, and a circle has infinitely many!

Square - how many lines of symmetry?

1Fold vertically ✓

2Fold horizontally ✓

3Fold diagonally ✓ (×2)

44 lines of symmetry

= 4

LEADER TIP

Folding paper is the most powerful way to teach symmetry. Have students fold and cut to make symmetrical shapes.
