Feature | Regular Shapes | Irregular Shapes |
---|---|---|

Sides | All sides are of equal length. | Sides can be of varying lengths. |

Angles | All interior angles are equal. | Interior angles can vary. |

Symmetry | Regular shapes are always symmetrical. | Irregular shapes may or may not be symmetrical. |

Examples | Equilateral triangle, square, regular pentagon, regular hexagon. | Scalene triangle, rectangle (non-square), irregular polygons. |

Definition | A shape with all sides and angles equal. | A shape with sides and angles that are not all equal. |

Predictability | Regular shapes have a predictable structure and are easier to study. | Irregular shapes have a less predictable structure and can be more complex to analyze. |

Tiling | Can tile a plane without gaps or overlaps using congruent copies. | Cannot tile a plane without gaps or overlaps using congruent copies. |

Mathematical Calculation | Easier to calculate area and perimeter due to uniformity. | Calculating area and perimeter can be more complex. |

Natural Occurrence | Less common in nature due to their perfect symmetry. | More common in nature, as natural forms tend to be varied. |

## How do you identify open and closed shapes?

Identifying open and closed shapes involves understanding their basic properties:

### Open Shapes:

**Definition**: Open shapes do not form a complete path; they have at least one “end” that doesn’t connect back to the starting point.**Examples**: A line or a curve that doesn’t join back to its starting point.**Characteristics**:- Ends do not meet.
- Cannot contain an area within them.
- Often used in diagrams or sketches to represent partial or incomplete boundaries.

### Closed Shapes:

**Definition**: Closed shapes form a complete path with all endpoints connected, enclosing a space.**Examples**: Circles, triangles, squares, and any polygon.**Characteristics**:- Ends meet to enclose a space.
- Can contain an area within their boundaries.
- Commonly used to represent complete, self-contained boundaries or areas.

The sum of the interior angles of a polygon can be calculated using the formula: $(n−2)×18_{∘}$, where $n$ is the number of sides (or vertices). This formula highlights the direct relationship between the number of sides a shape has, its vertices, and the total measure of its internal angles.

Here’s a table illustrating the relationship between a shape’s sides, vertices, and the sum of its interior angles:

Shape Type | Number of Sides (n) | Number of Vertices | Sum of Interior Angles |
---|---|---|---|

Triangle | 3 | 3 | $18_{∘}$ |

Quadrilateral | 4 | 4 | $36_{∘}$ |

Pentagon | 5 | 5 | $54_{∘}$ |

Hexagon | 6 | 6 | $72_{∘}$ |

Heptagon | 7 | 7 | $90_{∘}$ |

Octagon | 8 | 8 | $108_{∘}$ |

Nonagon | 9 | 9 | $126_{∘}$ |

Decagon | 10 | 10 | $144_{∘}$ |
