Watch on YouTubeVideoLine symmetry & axes
A line of symmetry (axis) splits a shape into two mirror halves.
- Square: 4 axes (2 diagonals + 2 mid-lines)
- Rectangle (non-square): 2 axes (two mid-lines)
- Rhombus: 2 axes (both diagonals)
- Equilateral triangle: 3 axes (perpendiculars from each vertex)
- Isosceles triangle: 1 axis
- Circle: infinite axes (every diameter)
- Kite: 1 axis (main diagonal)
Example
English letter "T" has 1 line of symmetry (vertical).
"H" has 2 (vertical and horizontal).
"H" has 2 (vertical and horizontal).
💡 Tip:A regular n-gon has exactly n lines of symmetry.
