Triangles, quadrilaterals, polygons — explore flat shapes! 🍭
A polygon is any flat shape with straight sides. "Poly" means many and "gon" means angle. So pentagon = 5 angles, hexagon = 6 angles! Honeybees build hexagon cells in their hives.
| Name | Sides | Special property |
|---|---|---|
| Equilateral | 3 equal sides | 3 equal angles (60° each), 3 lines of symmetry |
| Isosceles | 2 equal sides | 2 equal angles, 1 line of symmetry |
| Scalene | All different | All angles different, 0 lines of symmetry |
| Right-angled | May vary | Has one 90° angle |
| Name | Properties | Symmetry lines |
|---|---|---|
| Square | 4 equal sides, 4 right angles | 4 |
| Rectangle | 2 pairs of equal sides, 4 right angles | 2 |
| Rhombus | 4 equal sides, no right angles | 2 |
| Parallelogram | 2 pairs of parallel sides | 0 |
| Trapezium | 1 pair of parallel sides | 0 or 1 |
| Shape | Sides | Lines of symmetry |
|---|---|---|
| Pentagon | 5 | 5 |
| Hexagon | 6 | 6 |
| Heptagon | 7 | 7 |
| Octagon | 8 | 8 |
A regular polygon with n sides has n lines of symmetry.
A line of symmetry folds a shape exactly in half — both halves are mirror images.
Count the sides and look at the angles to identify a shape.
