### 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.
Let us now look at a few commonly known polygons.
