### Theory:

As of now, we are aware of triangles and quadrilaterals. We would have seen many triangular and quadrilateral objects in real life.

We know that a triangle is a three-sided figure, and a quadrilateral is a four-sided figure.

**So, can objects not have more than \(4\) sides**?

No, the objects can have more than \(4\) sides, and such shapes are called polygons.

**Polygon**:

A polygon is a closed figure with more than \(3\) sides.

Name | Figure | Number of sides |

Triangle | \(3\) | |

Quadrilateral | \(4\) | |

Pentagon | \(5\) | |

Hexagon | \(6\) | |

Octagon | \(8\) |
