Sides and corners of 2D shapes, including pentagons and hexagons, and lines of symmetry — with an interactive exercise.

We look at the sides and corners of 2D shapes.

A pentagon has 5 sides, a hexagon has 6 sides. A shape can have lines of symmetry — a square has 4.

Remember

  • Pentagon: 5 sides · Hexagon: 6 sides.
  • The number of sides equals the number of corners.
