Regular polygons and lines of symmetry

If you want to find the lines of symmetry, you have to remember that:

  • For regular polygons with an odd number of sides and vertices, each line of symmetry will pass through one vertex and the mid-point of the side opposite that vertex.
  • For regular polygons with an even number of sides and vertices, the lines of symmetry will pass through both pairs of opposite vertices and the midpoints of opposite sides.

So, the number of lines of symmetry is equal to the number of the sides of the regular polygon.
