REGULAR SHAPE SIDES Lines of Symmetry

Q. The number of lines of symmetry of a regular polygon is always the same as the number of edges. Q. Irregular polygons have no lines of symmetry

Lines of Symmetry Regular or Irregular?Hexagon

How many lines of Symmetry? Regular or Irregular?Hexagon

1. Regular polygons have the same numbers of lines of symmetry as the number of sides or edges. 2. Irregular polygons can have lines of symmetry.
